"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!"

“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.”
