The World’s Biggest Climb? | GCN Vs Alto de Letras

Close ×

The Alto de Letras is one of the world’s longest climbs, rolling for over 83km through the Colombian Andes to over 3000 meters and is a mythical cycling destination. Whilst in South America Si rode his bike up the mountain pass to find out what makes it so special, and why Colombia produces so many fantastic cyclists like Egan Bernal, Rigoberto Uran and Lucho Herrera. The climb itself might be a busy road, and if the altitude doesn’t leave you gasping for air, the stunning scenery will take your breath away….
