Tis the Season, for Gravel. What does it take?

By Grant Harrison

Tis’  the season, for gravel. But what does it take? The recent surge in popularity of gravel events over the past few years has my mind reeling. People are coming out of the woodwork ready to slay their own bodies over thousands of miles of gravel, in the dark, in the cold, and even when…

"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.”
