We Tried To Ride Up One Of The Highest Roads In The World

Si will lead a community ride on Rouvy up the Chacaltaya climb on Rouvy at 4pm BST / 5pm CET on Tuesday 23rd December, if you want to ride it with him. It will be a no drop ride!

Everyone that rides the Challenge | Chacaltaya Heights by GCN on Rouvy from 18th December - 1st February 2026, will receive a virtual GCN jersey 👉 http://riders.rouvy.com/route/252530 💥

Si and Ollie take on their toughest challenge yet, attempting to cycle up Mount Chacaltaya in Bolivia which stands at a staggering 5,421m (18,000ft). With 48% less oxygen than sea level, this gravel climb to the world's highest abandoned ski resort pushes them to their absolute physical limits. Can they conquer the extreme altitude and reach the summit, or will the thin air be too much?

In collaboration with @ROUVY 💥
