Sam Winebaum, Editor and Founder

Sam is a 1:38 half marathoner on a good day and didn't mind at all going into his 60+ age group in 2017. He has been running for 45 years and has a very dated marathon PR of 2:28.  Update: maybe he can still run fast as he clocked at 1:35 in 2017 and in 2018 a 3:40 Boston Marathon qualifier, surprising him.  He runs 30-40 miles per week along the New Hampshire Seacoast and on Park City, UT trails. Always a geek Sam was the Senior Contributing Editor for Wearable Fitness Technology and Music at Competitor Magazine and has also written for Motiv Running and China Fire Bulletin.

Peter Stuart
My running career got off to a slow start…in high school I was told I ran like a race walker and was thus relegated to race walking on the track team. I got back into running about 15 years ago and then into triathlon. Triathlon really rekindled my love for running, so about two years ago I hired a coach and really focused on the half and full marathons.  I broke a bad habit of putting in tons of moderately hard miles (and no or hard ones) and after plateauing at 3:25 (with some disastrous marathons in there), this past year I brought my marathon under 3:00 and my half under 1:25. Along the way I’ve developed a bit of a shoe problem.

Jeff Beck
Jeff is the token slow runner of the RTR lineup as such his viewpoints on shoe and gear can differ from those who routinely finish marathons in three hours or less. Jeff runs 40 miles per week, both roads and desert trails in Phoenix, Arizona. He has a PR's of 4:07 marathon and 5K at 23:39 both he is working to demolish with help from his coach Dave Ames and recently raced and finished his first 50 mile race.

Hope Wilkes
Hope is a lifelong resident of Northern Virginia. No stranger to hills and humidity, this mid-packer is most at home on tough courses that might make other runners stay in bed. Hope has dabbled in ultras, including two 50-mile finishes, but has turned her attention to the marathon, working hard to improve upon her 2017 PR of 3:47:40. Already passionate about sneakers when she picked up running in 2008, it was inevitable that she’d become a running shoe geek. Hope funds her shoe habit with her gig as a financial services trade association program manager, a job that includes regular domestic and international travel. This happily married mom of two cats is also a first-year evening MBA student at Virginia Tech. In her free time she likes to review running shoes and gear at her blog Runner’s Reviews [

Mac Jeffries 

Mac is from the Deep South and played small college football, earning All Conference his senior year. At that point, he was a 275 lb Defensive Lineman, but by the time his first child was born 7 years later, he was 275 again and pretty fat. P90X and a lifestyle change in eating habits got him down to the 220s, at which point his pastor challenged him to run a Half Marathon at age 29 - his first ever road race. Running and racing has been a healthy addiction that he has balanced with his wife, two sons, and teaching & coaching career ever since. Now at 6'4" 200lbs, Mac has PRs of 19:19, 1:33:xx, and 3:19:xx, and is engaged in the lifelong pursuit of convincing shoe companies to offer their premium shoes in a size 14.

Ryan Eller

Ryan decided to forego his Wall Street job to be a gear junkie, and is currently the fledgling entrepreneur behind his company, Bridger Helmets.  Most days, you'll find him loping along the Charles River in Boston.  Of all the places he's run, Central Park NYC and the New Hampshire coast top his list.

Along with skiing, he’s a big fan of endurance sports in general and does a lot of running.  He’s much faster at skiing, recently participating in the curtailed NCAA’s skiing for Dartmouth College, but can run a 4:43 mile (in trail shoes), 16:59 5k (earlier this week wearing the Sonic 3 Accelerates), and has won a few small trail races you’ve never heard of.  His mileage varies depending on how much snow is on the ground, but he trains about 700 hours a year including 1200 miles of running and 4000 miles of skiing and roller skiing.  You can follow him at his IG: @real_nordic_skier, his blog:, & on Strava

Renee is a former U.S. Marine journalist, which is when her enjoyment of running and writing started. She isn’t that awesome of a runner, but she tries really hard. Most of her weekly 50-60 miles take place on rural country roads in Nebraska, meaning mud, gravel, dirt, hills, and the occasional field. She runs a half marathon around 1:40 and hopes to get a full marathon at 3:30(ish) some day. Not today. But some day.

Nils Scharff

I am 30 years old, located in Heilbronn – Germany and married to my beautiful wife since last year. I’ve done all sorts of sports for all my life, often 5-7 times a week. But my young running career just started 3 years ago with a company run which I joined together with some colleagues in 2017. From there I never let go. I ran roughly 1000km in my first year, doubled and then trippled that number in 2018 and 2019. I've run 4 marathons to date with a PR of 3:14:49h. My other PRs are 18:14 for the 5k, 38:17 for 10k and 1:28:12h for the half. But besides chasing PRs and dreams on roads and trails, especially getting outside and escaping my desk is what makes my love for running (and other outdoor sports like hiking or climbing).

Joost de Raeymaeker  

Joost is a Belgian in his 50s living in Luanda, Angola, Africa, where he faces the heat, humidity and general chaos to run anything between 60-100 miles per week. He’s on a mission to win in his age group in the 6 Marathon Majors and has completed half of his project, with a 2:26:10 PB in Berlin in 2019 at 51. He ran in primary school, but then thought it would be a lot cooler to be a guitar player in a hard rock band, only picking up running again in 2012, gradually improving his results. His Strava is here:

Don Reichelt

Don is a competitive ultra runner based in Littleton, Colorado and is a veteran of many ultras including including 8 races of 100 or mile miles. Running highlights include a 16:27 100-mile trail PR, a spot on the 2017 US Spartathlon team, and a third place finish at the 2018 Badwater 135. While Don primarily runs trails in Colorado he also holds a marathon PR of 2:45, which he did mostly  to silence his road running friends about trail runners not being fast. 

When not running, you’ll find Don camping in the mountains, and enjoying time with his Wife and two dogs.

Jeff, I know you have been running in the Salomon Sense Ultra Pro. Salomon just launched it. Do you think it has more underfoot cushion than the Sense Ride?
