Colla del Termine cycling climb profile
Colla del Termine is a Category 2 climb in Italy that asks for patience more than panic. On paper, the climb is 12 km long at an average gradient of 5.21%, rising from 41 m to a summit elevation of 668 m. That makes it a real aerobic effort rather than a short punch, with enough vertical gain to punish riders who treat the opening like a threshold test.
The key number is the gap between the average gradient and the maximum gradient. An average of 5.21% suggests a controlled, tempo-friendly ascent, but the steepest section reaches 10.44%. That tells you the climb is unlikely to feel perfectly even from bottom to summit. The main demand is managing a moderate overall gradient while keeping enough reserve for ramps that briefly move into double-digit territory.
How the gradient unfolds
The climb starts low, at 41 m, and gains 627 m net on the way to 668 m. Across 12 km, that creates the basic shape of a sustained ascent rather than a single violent wall. The available profile data does not place the steepest ramp in a specific kilometre, so the safest way to ride it is to assume the hard sections can arrive before you feel fully settled.
That matters tactically. A climb averaging just over 5% can tempt riders into riding a gear too large early, especially if the road feels manageable at the bottom. But on Colla del Termine, the 10.44% maximum gradient changes the cost of that mistake. If you arrive at the steepest pitches already over threshold, you will be forced into a low-cadence grind, and the final part of the climb becomes damage control rather than controlled pacing.
Pacing and gearing notes
Ride Colla del Termine as a long, measured climb with short stress points. The right approach is to settle into a sustainable rhythm early, keep the effort below the level you would use for a shorter climb, and let the gradient spikes come to you.
Practical execution:
- Start conservatively. The 12 km length gives small pacing mistakes plenty of time to compound.
- Keep cadence flexible. The 10.44% maximum gradient means you need a gear that lets you stay seated when the road steepens.
- Avoid chasing speed on easier sections. Use them to stabilize breathing and bring the effort back under control.
- If using power, anchor the climb around a sustainable climbing effort rather than reacting to every change in gradient. See /glossary/ftp if you pace climbs by threshold.
Bottom line
Colla del Termine is not defined by one extreme statistic, but by the tension between its manageable average and its sharper maximum gradient. The winning ride here is disciplined: smooth early, responsive on the steepest ramps, and never so overgeared that the climb dictates your cadence for you.
