Alto El Sifón from Armero

Tolima, colombia

Alto El Sifón from Armero is one of cycling's great tests — 87.9km of sustained climbing, gaining 4,015m from base to summit. Averaging 4.6%, the road kicks to 8.8% at its steepest — a notable steepening that demands respect. This is a climb of endurance — the kind of effort measured in hours, where pacing matters more than power. The summit at 4,124m sits above the treeline, where the air thins and the views extend to distant peaks. Located in Tolima, Colombia.

  • One of only 119 Super Hors Catégorie climbs in the database.
  • Summit above 4100m — expect thin air, snow into early summer, and conditions that change fast.
  • A false flat around km 17 offers brief respite before the road kicks up again.
