I challenged himself to do a full effort, max power 107 seconds sprint. Thats 1 minute 47 seconds. In running terms, dependant on the runner we are talking a sprint for 500 to 800 meters to make that a bit easier for you.
Hooked up to my Infocrank and on Jimmi's Wahoo Kickr on the bike to get some accurate information regarding his power. I have had a few goes at this previously creating anything from 500-570 watts for his max effort. Whatch what happened in the video below by Francis Cade.
