The climb actually began from a flat plain, altitude 3075m, but this recording starts in the town of El Penon at 3400m, climbing continuously to the summit at 3999m. At around 3575m, the gradients ramp up and the wind morphs into powerful, swirling cold gusts that make it a struggle to keep the pedals turning and the bike on the road.
Surface - asphalt, but extremely rough with high rolling resistance.
