Tackling the Hell of the East (Coast)

By Adam Mills | June 23, 2022

Just six short weeks after the first Belgian Waffle Ride in San Diego, the second stop of the Quadrupel Crown of Gravel took place. This time the traveling gravel circus took roots in the East Coast, somewhere about 30 miles south of Asheville, North Carolina along the border of South Carolina. BWR North Carolina was…

Preparing for the Hell of the North (Carolina)

By Adam Mills | June 9, 2022

It’s been about one month since Belgian Waffle Ride (BWR) California and now North Carolina is right around the corner. I thought I would have a solid window to prepare for what’s to come at the next BWR but honestly, I’ve been on a crit racing calendar, so the preparation is, well, being handled differently.…

How to Avoid DNFing the BWR

By Adam Mills | June 1, 2022

Many begin an epic adventure like the one you’ve just embarked upon expecting moderate discomfort and glory to await us, but only the most prepared will triumph over the Belgian Waffle Ride. Although the numbers are not public, we know a high percentage of riders never cross the finish line and get their own ride…

"My work/life balance has not always allowed me to train/race or even ride as much as I would like. I appreciate my coach for his willingness to adapt to my challenging schedule so that I am able to enjoy my limited time on the bike without feeling guilty or frustrated for having a lack of fitness. Adam and Source Endurance have been a great partner for the past 10 years both on and off the bike!" 

- Patrick Robinson

“My season goal was to finish DK200.  Goal crushed.  I can’t say enough how well the plan leading up to Dirty Kanza worked out.  Perfect on so many levels, I was beyond ready mentally and physically, evidence by beating my DK goal by almost 2hrs.  BWR challenged me technically, but the rest was a piece of cake in terms of my readiness for the duration and heat.”

– Sonja Johnson

“I’ve loved working with Grant and Source Endurance so far, really happy wtih the results I’ve been seeing this cross season!”

– Alex Edwards

“Just wanted to say the year is turning out okay despite rocky winter. Steady build has me seeing power numbers as high as I’ve seen in a decade. Now onward to DK 200. Thanks for the guidance!”

-Trey Harrison

“Basically just writing to say a big thank you.  I truly don’t think my performance would be where I’m at without the training regimen you provided. During those primes and sprints I felt unstoppable.  I was calculated, composed and even more importantly, coached, on exactly what I needed to do.”

-Chris Lowry- La Crosse, Wisconsin
