Then in 2024, he broke Matt Carpenter’s 19-year-old Leadville 100 Mile course file by greater than 16 minutes. Satisfied about the advantages of treadmill coaching for ultras and uninterested in utilizing treadmills he didn’t love, he bought a Wahoo KICKR RUN on the advice of different runners. Now a Wahoo Health-sponsored athlete, Roche doesn’t attempt to include his enthusiasm when recalling his then sticker-price buy: “I used to be form of obsessed instantly. You set this factor all the way down to its most four-minute tempo, and it doesn’t bounce in any respect. It doesn’t make any noise.”
Later that yr, Roche went on to win the 2024 Javelina 100 Mile, and in 2025, he reset the Leadville 100 Mile course file by one other 14 minutes. Roche is fast to credit score the treadmill for his success, saying, “I’m scared to consider how my private athletic journey may need unfolded as a result of, for the longest time, I used to be identical to, ‘I’m only a coach, and the racing I do is secondary to that.’ Then I began utilizing a treadmill and located high-carb fueling, and hastily, I’m so significantly better than I believed I might be.”
Roche, who, alongside his spouse Megan Roche, coaches high runners together with Hans Troyer, Anna Gibson, Tara Dower, and Jess McClain, started incorporating uphill treadmill work into the programming he gave his athletes. He admits, “The treadmill is a type of coaching instruments that I really feel a little bit uncomfortable speaking about as a result of I nonetheless suppose it’s one of many solely secrets and techniques we’ve got left, the place our athletes have some benefit nonetheless as a result of everyone hasn’t dedicated to it in the identical means we’ve got.”
However in response to Roche, a high quality treadmill just like the Wahoo KICKR RUN isn’t only for the elites: “The place it may need essentially the most good thing about all is for ageing athletes. We coach 50-plus-year-old athletes, who, with the treadmill, can do classes that they may have been in a position to do after they had been 25, and really feel like one million bucks the subsequent day.”

They’d the identical end result.
Roche says, “I began experimenting an increasing number of, to the purpose that it turned a secret weapon for some time for our athletes.

For a lot of runners, operating quantity earlier than physique breakdown and time accessible for coaching are their two essential limiters.

And also you’re getting that with out the impression of doing that exterior, the place should you’re pushing that regular reasonable zone, you’re simply going to get beat up and decelerate a little bit bit.”
