He Beat an Olympic Mountain Biker Up Snowdon
Red Bull put Tom Evans on foot against Tom Pidcock on a bike. Seven kilometers of Yr Wyddfa settled it.

The premise was simple and slightly insulting to one of them: an ultrarunner and a double Olympic mountain bike champion, the same seven kilometers up Yr Wyddfa, go.
Pidcock had gears. Evans had the gradient. Inside the last two kilometers, where Welsh rock stops being rideable and starts being a staircase, Evans was simply gone.
Seven kilometers up. The bike lost the last two.
