Do you need big legs to push watts? A friend asked whether good hill climbers would need giant legs to push big watts---450-500W for a light rider, or 6--6.5W/kg. Apparently not. Phil Gaimon is a very strong hill climber. He looks like this. <img src="https://fascatcoaching.com/wp-content/uploads/2016/02/tips/Phil-Gaimon-Cannondale.jpg" width="100%"> Scrawny A.F. Not so huge legs, though. In the next video, you'll see that he can push 450-500W for minutes at a time. The first video is of Fabian Cancellara vs. Phil Gaimon. Both can push big watts, but Gaimon is retired and weighs about 20kg less. It wasn't really a fair fight, but still amusing. I was at this ride in Wallis, Switzerland but only rode with Cancellara and Gaimon at the very beginning---before they took off up the Col des Mosses, the 20km HC-climb just before this one. <media src="https://www.youtube.com/v/s2oxyIYjNmY" href="https://www.youtube.com/watch?v=s2oxyIYjNmY" caption="Complete Race: Phil Gaimon vs. Fabian Cancellara" width="560px" source="YouTube"> Next up is a video of a short hill-climb in San Fransisco. The winner pushed crazy watts (787W average) for 77 seconds to win. <media src="https://www.youtube.com/v/XPaHJerZ9dU" href="https://www.youtube.com/watch?v=XPaHJerZ9dU" source="YouTube" caption="Outclimbing Phil Gaimon -- 2018 Red Bull Bay Climb" width="560px"> Finally, here's a video of a track cyclist vs. a road cyclist. Crazy watts again. They compete in several categories, from 6 seconds to a 5km hill climb. If you want to push over 2000W for a short period of time, then you'll need giant legs. Otherwise, light and strong is the way to go. <media src=" https://www.youtube.com/v/PCLvqN9kwuo" href=" https://www.youtube.com/watch?v=PCLvqN9kwuo" width="560px" caption="Road Cyclist VS Track Sprinter (Who's the better cyclist?)" source="YouTube">
