Criterium Workout of the Week: 30-30s

By Adam Mills | March 21, 2023

We like to use these 30-30s or Tabata intervals to really engage an athletes anaerobic system. The explosive efforts are short and unsustainable and coupled with a rest that’s incomplete this workout really quenches the big power thirst of criterium racing.

Mid South: Becoming Faster and More Spicy

By Adam Mills | March 20, 2023

The quality of the athletes at the pointy end of races like the Mid South has dramatically improved. Gone are the days where local heroes battle it out for glory amongst the rare traveler from far away lands. The time is now and the races resemble more of a Monument than they do a gravel race.


Orucase Updates Airline Bike Fees Information to Help Travelers

By Adam Mills | March 16, 2023

Traveling with a bicycle can be a thrilling experience, whether you’re touring the countryside, exploring new trails, or competing in a race. However, when it comes to air travel, the cost of transporting your bike can quickly add up.

"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
