A World Record Racer Story: Camille Herron's Journey to the 100 Mile World Record. In depth- the training, science, and drive to the record

Article by Sam Winebaum
Photo Credit: Conor Holt

Camille Herron recently shattered the world 100 mile record by over and hour, running 12:42:39 at the Tunnel Hill 100 (Illinois), winning the race outright by 20 minutes and 10 minutes faster than anyone ever on the course. It was her first hundred mile finish. The Tunnel Hill 100 mile race on a rail trail corresponds to approximately 4 marathons run back to back to back at 7:38 pace. Put another way each of these 3:19 marathons, one after the other, is a Boston Marathon qualifier for her age group, by about 10 minutes each!

Not a week removed from her race, Camille sat down with RoadTrailRun where she graciously, at length and in depth discussed her running career, training and recovery techniques, racing strategy, and of course shoes.

I first met Camille online at the Running Shoe Geeks on Facebook several years ago where she was, and still is, is an active participant, asking technical shoe questions and always also freely answering any and all questions. These days Camille is sponsored by Nike and raced the VaporFly 4% at Tunnel Hill. She runs Terra Kigers on the trails. Of course we discussed her shoe selection for Tunnel Hill, the Nike Vapor Fly 4%, and how they performed. We learned she ran almost all her prep miles in a pair, 450 miles in a month or so, then tuned up a fresh pair with a few runs running the new pair at Tunnel Hill.

Hoka One One Mach Review: Much More Than a Clayton Name Change

Article by Dominick Layfield and Sam Winebaum

  Sam: 7.9 oz/224 sample size US M9
  Dom: 8.2 oz/ 244g US M10
Stack Height: 24mm heel/ 19mm forefoot stack, 5mm drop
$130. Available February 2018
Sam: The Mach is the direct successor to the Clayton and shares many similarities with it. It is part of Hoka new Fly performance line which includes a similar weight and stack performance trainer the Cavu (RTR review) and a renamed and re thought Vanquish now called the Evelon. All feature Hoka’s ProFly dual density midsole (softer in the heel and firmer in the forefoot)  and engineered mesh uppers. At first I was skeptical that this "renaming" of the Clayton was just that, but there are enough changes to make Mach an almost "new" shoe, worthy of consideration for those who had issues with the Clayton's upper and especially where it met sockliner and midsole with its tendency to cause arch blisters as well as those who felt Clayton transitioned a bit stiffly as I did.

Dom: Hoka could have gone either way calling this the Clayton 3 or using a new name.  Ultimately I think this is the right call: personally, I always got confused between similar-sounding Clayton and Clifton names.  Additionally, I think they wanted to distance themselves from the legacy of instep blisters from two iterations of the Clayton.  

First Impressions Sizing

Sam: The many thin overlays and bright colors of the Clayton 2 were a bit over the top. The modern sleek look here is classy and best of all the engineered knit upper is highly functional in how it distributes support without any overlays and is for me a big improvement over the Clayton’s plasticky and somewhat stiff upper.

My sample size 9 was half size up from my true to size and I could have easily stayed at true to size, especially with thinner socks. I find the Mach slightly pointier than the Clayton, worn side by side, but in no way was this an issue for me, or likely for most as the Mach upper is a softer if dense mesh but more open and foot shapes friendly than Clayton with no overlays and with very decent overall foot hold.

Dom: I really like the look of the Mach.  In my opinion many Hoka shoes have looked unduly busy, with many different color fades, overlays, conspicuous logos etc.

Under Armour UA Charged Bandit 3 Review: Handles Biz!

Article by Peter Stuart

The Under Armour Charged Bandit 3 weighs in at 8.4 oz/238 g for a men's size 9, 7.6 oz/215 g for a women's size 8. 
They have an 8mm offset according to Under Armour. Running Warehouse measures the shoe at 29mm heel and a 19mm forefoot for a 10 mm offset while Runner's World puts it at 10mm with a heel stack height of about 32mm and forefoot of 22mm. Regardless of which measurement is correct, likely differing in how each treats the sock liner in the measuring mix, for sure we have a lot of cushion stack for the light weight.

First Impressions and Fit
I haven't had great experiences with Under Armour shoes before, so my expectations here weren't high. The Gemini was meh and I found the Velociti pretty much unrunnable. Imagine my surprise when the Bandit 3 sneaked to the front of the line in my running shoe rotation. My first run in them was, surprisingly, one of the more fun runs I've had this year.

Mizuno Wave Rider 21 Review: Strongly Divided Opinions

Article by Dave Ames with Peter Stuart

Mizuno Wave Rider 21
Stack Height 30mm heel / 18mm forefoot, 12mm heel-toe offset
Men’s Size 9 (9.6 oz/272 g) - - Women’s Size 8 (8.3 oz/235 g) (Running Warehouse)


Dave: In addition to several smaller updates, the Mizuno Wave Rider 20 received a new wave plate and a U4icX foam heel wedge that give the shoe a softer landing and added responsiveness. Building off of those updates, the Mizuno Wave Rider 21 retains the midsole and outsole design of the Wave Rider 20 while incorporating a reformatted upper and a new, premium sockliner that should improve the fit and comfort.

Because of the new design, the men’s Wave Rider 21 weighs 0.8 ounces less than the previous version while the women’s weighs 0.3 ounces less.

My all time favorite Mizuno Rider was the 13, a bunch of years back.  (Editor Note: It was our Wave Rider 20 reviewer Coby's as well see his RTR review). This is a shoe I continuously used (14,15,16,17, etc) as my go to trainer, back when I was younger, fitter and trained a hell of a lot harder!  Over the years, the Wave Rider series began to get stiffer and stiffer in the wave plate and I steered away from the brand as I began to be intrigued and “brain washed” by the lower drop movement that began to take the run specialty biz by storm.  Note:  It’s been a bunch of years since I have run in a Mizuno, so I was happy to take the lead via Sam on this one and give the all new 21 a try!

Peter: Dave, I too loved the Wave Rider 13. That was a terrific shoe--it’s been a while but if memory serves it was a great mix of cushion and snap. I have occasionally tried on a Wave Rider since, and may have bought one--but I’m sure I returned it. I was excited to try a new Wave Rider and hoping for a good utility shoe.

An update to the 20, the new 21 uses a new Dual Zone Mesh in the forefoot to improve breathability and flexibility.  

The heel collar has also been softened for increased comfort.  A new anatomical sockliner was added as well for better underfoot and feel.   
Dave:  Upon initial step in the Rider 21, feels quite nice.  The upper worked extremely well in molding my foot and noticed no immediate issues where hot spots could occur.  I am a size 9 in trainers and I did notice that it was a tad small on me (felt better as I ran) - - but I may suggest going up a half size in this shoe.  The shoe laces were a bit long.
Peter: Step-in to the 21 was nice. The shoe feels cushioned, the upper holds the foot well and my hopes were high. True to size for me.


The midsole in the 21, shadows what worked well in the 20, just simply adding a better upper around the foot.  To maintain the lightweight and responsive ride of its predecessor, the Wave Rider 21 includes U4ic midsole foam with a U4icX heel wedge to offer responsive cushioning and a soft landing under the heel. It also incorporates an identical Cloudwave plate for additional underfoot spring.

Dave:  I was pleasantly surprised by how powerful the Rider 21 was after a few runs.  The Cloudwave plate in the forefoot allowed for a significant amount of pop, and gave quick heel to toe transition on both easy mileage days and a tempo day for me.   

Peter: There’s SO. MUCH. MIDSOLE on this shoe. There’s the plate, the foam, the wedge. Oy Vey. The drop is epic at 12 mm and the heel feels really built up and plastic-like. There might be some decent foam in there, but I couldn’t even feel it as the whole midsole feels so stiff to me that I can’t get a decent stride.

Dave:  Here’s where we run into a problem.  The shoe is extremely loud!  Like “slappy” loud...even walking around in it.  The beefed up outsole, combined with the stiff wave plate make this thing hear you the runner coming for miles.  Not sure I could get used to that all the time while running.  Note: I just paid attention to nature and my mind drifted away from the musical symphony on my foot.  Durability wise, I can see that this shoe will be built for the long haul, compared to previous Rider models.  It is a high mileage trainer for sure.  

Peter: Yup, they’re loud and, for me, feel incredibly graceless. Every step I’ve taken in these shoes has been a fight not to turn home to get different shoes on. Again, there’s so much going on that I can’t even feel the road--but I can sure hear it.

Dave:  Other than the shoe being loud upon footstrike, I am quite pleased with the overall ride of the Wave Rider 21!  It brings back many memories of way early models, which I absolutely loved.  Mizuno struggled for a few years with the Rider, but in my opinion it’s back and feels great.  I had some great runs in it (easy miles, tempo) and plan on using it throughout its entire life cycle in prep for LA Marathon 2018.  It’s extremely smooth and boasts a solid heel to toe transition.  My gait has some pop to it, which I love coming from a trainer.

Peter: As you may have figured out by now, I do not like the ride of the Wave Rider. The ride of these is stiff, clunky and unforgiving for me. I’m glad to see that Dave likes them--and it’s nice to remember how subjective running shoe reviews can be. For me this shoe is a non-starter. I fear having to run in them again.

Conclusions and Recommendations

Dave:  My only issues with the shoe in terms of fixes would be how can we make this thing not be so “slappy?”  The shoe laces were a tad long for me and the colorway was a bit, blah.  But in terms of sales, greys and blacks are safe and I know this baby is selling.  At the $120 price point this is a solid daily trainer for anyone looking for a solid smooth shoe.  It’s perfect for easy recovery days and your long runs, but also felt decent (I was skeptical) when kicking it uptempo.  I’ll pull it again for another threshold day for sure.

Peter: As I mentioned in the ride section above these are not the shoe for me. I couldn’t get any rhythm or joy running in them. There’s too much shoe for me and they feel like they work against my stride. It’s a bummer.


Mizuno Wave Rider 21 vs. Skechers Performance Go Run Ride 6:  
Dave:  Though on completely different platforms, I found these 2 shoes to be quite similar.  Very stiff with a ton of snap.  I’d say the upper advantage goes to Skechers Performance on this one, but it’s very close.  You'll pull a tad more room in the toe box in the Ride 6.  Mizuno durability wins out.
Mizuno Wave Rider 21 vs. New Balance Vazee Pace
Dave:  If we’re talking firm here, these two will go head to head.  While Vazee Pace has been on the shelves for a bit, I almost get the same feel from both of these shoes.  Both providing a nice forefoot snap, which I absolutely love in the trainer.  Both lock you in well in the heel and have a solid midfoot fit.  Durability goes to the Rider 21.

Salomon XA Elevate Review: Handles all terrain, at any speed with exceptional aplomb, protection and comfort.

Article by Jeff Valliere, Larisa Dannis and Sam Winebaum

Salomon XA Elevate
Weight: Test sample in US M9:  10.7 oz/304g
              Production: 10.4 oz/295g (US 9M) 9 oz./255g (US 7W)
Stack Height: 25mm/17mm (8mm drop)
Lug Height: 5mm
MSRP: $130
Available December 2017 at REI in the US, general distribution March 2018


Jeff: The XA Elevate is a versatile, rugged, all mountain shoe It has a a secure internal Endofit upper
grippy outsole with aggressive 5mm lugs, Salomon Premium Wet Traction Contagrip rubber compound, a forgiving, yet precise fit and exceptional breathability. 

The XA Elevate is about a quarter ounce heavier than the Sense Ride and appeared to me at first glance to be somewhat redundant, but the XA Elevate sets itself apart with more forgiving cushion, better protection (much credit to the thicker Profeel film rock plate), better traction and a more stable ride.

Though cushioning is on the firm side, it offers a level of rock protection and stability that is hard to beat.  The firm ride essentially goes unnoticed in mixed terrain, but was somewhat evident at faster paces on hard, smooth surfaces (i.e. roads, cement paths or bulletproof compacted dirt).  The moderately aggressive tread, coupled with Salomon’s premium wet traction Contagrip rubber compound helps the XA Elevate to excel in a wide variety of terrain and conditions, no matter ones running style. 
Sam: The XA Elevate comes out of Salomon's more hike focused XA line. Don't be fooled by its hiker vibe this is one heck of a versatile trail runner. I found that the XA Elevate was able to handle everything from steep, slippery, rocky and rooty New Hampshire trails taken hiking to smooth single track on the run, even roads are just fine. It has an exceptional ride  due to its long smooth flex and its responsive yet cushioned if firm ride. The only place it was a bit labored for me was on very steep climbs taken running due to the front stiffness.

Larisa Dannis's Racer Story- Lessons from the mountains: reflections on a run at the Javelina Jundred

Article by Larisa Dannis

Editor's Note: We are thrilled to have Larisa share her journey from her beloved New Hampshire mountains to the top of the ultra world while living in fast paced California, including 2nd at the 2014 Western States 100 in an injury riddled chase of results.  In early 2017, she returned home rebuilding and enjoying her NH mountain trails leading to a happy smooth return to the top of the podium at the Javelina Jundred last week: 1st woman, 6th overall, 16:32 with a qualifier for the Western States 100.
The most beautiful trophy I've ever won

The mountains are powerful teachers if one is willing to pause and heed their lessons. This is especially the case with my home range: the White Mountains of New Hampshire. Beautifully and brutally technical, they reward patience and consistency above all else. Go out too hard and you likely won’t recover, especially as the distance of your route increases.

My ultrarunning career was born in the mountains. I built up my endurance and my fortitude through years of distance hiking. Traversing those rugged White Mountain ridgelines instilled in me a deep understanding of my body and the various effort levels I can sustain. The mountains kept me grounded and made me strong. They taught me the importance of staying in the moment, of appreciating the journey and the process.

When I moved away from the mountains in the summer of 2014, I lost touch with who I am. I lost my ability to be patient. I started to chase immediate results. Turning a blind eye to the advice of many who kindly guided me, I buried myself into the ground, and by the beginning of 2017 I’d burned out – hard. After hitting rock bottom, one has two options. She can give in, or she can resolve to get back up.

I chose the latter.

Within a month of making my decision, I was back in New Hampshire. That first weekend home, I returned to the mountains. For the first time in years, I felt at peace.

Five Tester 2018 Hoka One One Cavu Performance Trainer Review

Article by Shannon Payne, Sam Winebaum, Peter Stuart, Derek Li and Dave Ames

Editor's Note: We are thrilled to welcome Shanon Payne to the RTR review team in this her first review. Colorado based Shannon is a 2 time winner of the infamous Mt Washington Road Race including 2017, a past member of the US Mountain Running Team placing 3d in the 2014 World Mountain Running Championships long course ascent of Pike's Peak, and was a 7 time All-American in track and cross country at University of Colorado, Colorado Springs.

The all new Cavu ($110), 8.2 oz/221 g men's size 9, 6.6 oz/188g women’s size 8 has a 24mm heel/20mm forefoot stack, 4 mm drop. Available February 2018
Cavu is intended to be a light weight performance trainer. It is called out by Hoka as being "a little lighter and a little lower than its category mates." which we assume to mean the new Mach (RTR initial impressions and comparisons to Cavu here, full review soon). Mach Update: Read our full review of the 2018 Mach here is a direct successor to the Clayton 2 which weighs a tiny fraction of an ounce more and has 1 mm less forefoot stack height. Another Hoka to compare the Cavu to is the Hupana (RTR review) with its near identical 25/20 stack and slighter heavier weight at 8.2 oz.

The Cavu features Hoka’s new dual density ProFly midsole, softer in the heel firmer in the forefoot for protection and propulsion.  ProFly is an evolution of the similar Pro2Lite midsole makeup found in the Clayton 1 and 2 (RTR review), Tracer (RTR review), and Speed Instinct 2 (RTR review) but with a new foam. This new midsole material is designed to be more resilient and energetic/energy efficient and attenuate shock better.

Where the rubber hits the road Cavu features Hoka’s soft, durable, and bouncy RMAT, a material sometimes used in Hoka midsoles such as in the Hupana, also a light weight performance trainer (RTR review) where both midsole and outsole are a single slab of RMAT but here now only used as an outsole.

The upper is a new relatively unstructured engineered mesh and unlike many Hoka such as the Clayton or Mach there is a less pronounced “bucket seat’ for the heel and a real heel counter so this is a more conventional design.

Epson ProSense GPS Watch Line Launches. Initial Review- ProSense 307 GPS/Wrist HR Watch with Incredible EasyView Display

Article by Sam Winebaum

Epson just introduced its all new ProSense line of running and multi-sport watches. The 5 models range in price from $99 for the GPS only ProSense 17 to the $399 ProSense 367 with its sapphire crystal, up to 48 hour GPS and HR run time and a crisp glare free electronic paper EasyView display. All offer a very complete feature set for serious run training, impeccable engineering and very compelling price points.
In brief the line can be summarized as follows: 
ProSense 17 color choices
ProSense 57 color choices
 The 347 and 367 are available in black only at this time
ProSense 347
All watches, except the GPS only 17 add  Epson highly accurate GPS in house built wrist heart rate modules. 

Epson is a leading manufacturer of sensors and its highly power efficient GPS modules, called RouteSense GPS in the ProSense line and tuned for running, is used in many mobile phones. We saw excellent accuracy and battery life in the earlier RunSense line of Epson watches. And let us not forget sister brand Seiko is one of the largest manufacturers of watches in the world, so a powerful combination,

As Epson manufactures its own components the integration is completely controlled in house, a key factor in the very long battery life,accuracy, and price. Integrated to the GPS are position algorithms and stride sensing which allow the watches to also give live stride length and cadence stats.  It turns out Epson athlete Meb Keflezighi is a big proponent of evaluating stride length and cadence and the ProSense includes by default just such as screen as seen below, 

On the heart rate sensing side, the CardioSense wrist optical heart rate sensor includes noise cancelling sensors,tuned algorithms as well as a Transimpedence Amplifier allowing the watches to measure HR from the wrist in pools, a rarity. Apparently because algorithms are also tuned for water temperature to pull this off Cardio Sense may not be as reliable for open water swims. We have not tested in water yet but have found accuracy on the run to be excellent.

EasyView Screen
The defining feature of the 307, 347, and 367 is the unique in my experience EasyView "electronic paper" display. The electrophoretic eInk style display mimics paper and is very easy on the eyes.  The monochrome display was incredibly crisp and glare free in all light conditions during my testing. The EasyView screen is by far most visible, glare reducing, crisp and easy to read screen of any I have run with to date. Instead of emitting light like more conventional displays the display reflects light. The screen only updates areas/digits which change and is instantly awakened backlight coming on by any turn of the wrist and flawlessly so. 

Epson ProSense 307 ($249)
ProSense 307
We have been testing the mid range ProSense 307. It weighs 49 grams so similar in weight to the new Garmin Vivoactive 3 (see our YouTube video description here) or Forerunner 935 but far lower in price than the 935 and with a longer spec battery life at 20 hours than the Vivoactive which is rated at 13 hours.
The 307 has a decidedly retro "training watch look. If you want a more rugged modern look,  a mineral glass cover and the 48 hour battery life consider the 347 at $349 or the sapphire crystal 367 at $399. All other features other than battery life are the same are the same and all three the 307, 347, and 367 share that incredible EasyView screen

There is another reason beyond style and battery life to consider the 347 or 367.. We found the flat buttons on the 307 somewhat hard to find and decisively press on the run to change data screens. The 347 and 367 have more prominent "sharper" buttons (see below). Not to worry, the watches have auto scroll of screens as well as a feature that changes to the next the screen with each flick of the wrist.
The 307, 347, and 367 feature a soft, stretchy, quick release Pro Silicone band so it will be easy for me to change out the somewhat clashy blue band on the test watch. The band is very comfortable and easy to cinch to the right pressure to get accurate wrist heart rate readings.

Fit and Band

At 49 grams the 307 is light on the wrist and fits my thin 6" diameter wrist well. 

The Pro Silicone Band has a quick release feature. The tiny silver pins can be pushed sideways to easily release the strap. Charging and computer synching is via a fairly large clip style unit which wraps around to the front from the 4 bronze colored charging pins. 

I can't wait to swap my blue front back black band for an all black one!. The look is a bit to retro and old school for me. 
Back to serious the band is stretchy and soft and assures a comfortable snug fit to my wrist, the snug part essential to getting solid wrist based optical heart rate readings. As with all wrist heart rate watches, it is recommended to wear them on your dominant wrist,

Battery Life 
The battery life appears to be on the low end of the spec in daily use. I say appears, as the battery gauge as far as I can tell is only visual, no percentage view. I believe the reason for this lower battery life is that I have the heart rate sensing set to Continuous which is a sample once a second 24/7. Continuous is required for the basic but excellent on watch sleep tracker to function. The Automatic option measures for 2 minutes out of every 10 minute activity period.  Activities are distinguished from Workouts such as running where heart rate is measured continuously. 

While there is a cycling mode 307 does not appear to support external sensors.

The ProSense watches do not have a barometric altimeter. It uses GPS to estimate elevation and ascent/descent stats. I have not been on sufficiently vertical terrain to evaluate its accuracy vs. a barometric altimeter watch but did note on one hilly run that my Garmin 935 with its barometric altimeter  run in parallel had my starting elevation considerably higher than reality or the 307's reading. 
There is no route following "breadcrumb" navigation but you can preset waypoints in the app and the watch will notify you of your progress towards them. We have not yet tested this feature but will do so in our full review.

Epson View
Not content to just completely update the watches, Epson also completely revamped its app and web site. 

All the watches can synch and be configured via Bluetooth from the phone app, sometimes not the case for lower cost watches such as the ProSense 17,  or directly connected to the computer. The "view" of data and configuration options is almost  exactly the same in both places so no need to learn two different views, nice touch. Pre launch we found the phone to watch occasionally delayed or failing to connect more than I would like to see but not unusually so. Many other watch to phone Bluetooth connections seem to take their sweet time.

Configuration of all data fields and settings is very easily done via the app or when directly connected to a computer.  I did find configuring intervals not as intuitive as I would like. Still working on figuring that out and will update the article when I do. I will also test the various run to target options such as pace and heart rate as well as the special race set up. There are a tons of features to explore and use here,
Stride length measurement is a special on board feature of the ProSense watches. Meb likes to compare Stride Length to Cadence and Heart Rate and special default screen is included to do this.

Workout stats are clearly presented and complete.  While easier to analyze in the web browser view, you can select any two stats in the app and run your finger along the graph to see how all stats change over the run in the data boxes.

With an intense enough effort, 50% of Heart Rate Reserve HR which is  the difference between your resting and maximum heart rate, with auto pause off and for a minimum of 10 minutes, the watch will estimate your V02max. I neglected to turn off auto pause so it did not calculate or maybe I did not run hard enough that day!

There is a solid daily view of all activity and sleep which is separate from run stats views.

The sleep module conveniently makes sure that within your pre defined sleep times that the screen does not light up in the middle of the night unexpectedly as you move. Setting pre defined sleep times is not necessary but increases accuracy. 

All the watches have adequate, if basic "smart watch" features of activity and sleep tracking, phone notifications and music control.

Data can be shared to platforms such as Strava and Runkeeper. 

Epson has done something bold with their new ProSense line. The new line delivers:
  • truly outstanding battery life with the 367 getting as much as an astounding 48 hours of GPS and wrist HR in the ProSense 367 
  • a highly visible, low glare EasyView electronic paper displays on 3 of the models: 307, 347, and 367 is the best I have seen yet in a GPS watch and is instantly readable in any light condition,
  • high accuracy sensing for GPS and  heart rate even in water, along with stride length and cadence sensing. 
  • deep capabilities to configure the watches for serious multi sport training needs of any flavor or philosophy
  • basic smartwatch features of activity, sleep, music control and notifications on all models
  • very compelling prices from the basic GPS only ProSense 17 at $99 to the sapphire crystal 48 hour  battery life ProSense 367 at $399,
The mid range 307 tested with its retro looks is all business and serious training focused. At $249 it provides about as full a feature set as the serious runner and multi-sport athlete could want. It includes the now requisite smart watch features, and then to tops if off with a 20 hour battery life and an outstanding display. So we have great performance and great value, a rarity for any product.
