Think the Peaks Challenge is a big day out? Terrified by the thought of Everesting?

That's all child's play to American Craig Cannon, who ended up climbing 29,146m in a single - albeit mammoth - 42-hour, 546km ride on 7 and 8 August.

“I finished the ride in 13 or 14 hours and I still felt good, so I thought maybe I can do something longer,” Cannon told NBC Bay Area.

By reaching 95,622ft of ascent he broke the previous record of 95,452ft as the most climbed in a 48-hour period. And, if that wasn't enough, he started the ride after running a half-marathon.
