"In the two weeks leading up to CXNats, Kristen and I worked on balancing getting in the running and hard, punchy efforts that would be required for the Hartford course, and making sure I was fresh and recovered on race day. And you know what, we nailed it..."

"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!"
