Tera Pass

Tera Pass cycling climb profile

Tera Pass is a long category 2 climb in AF, rising from 2060 m to 2894 m over 23.2 km. On paper, the average gradient of 3.59% makes it look controlled rather than severe, but that headline number does not tell the full story. The maximum gradient is 10.02%, which means the climb is not a simple metronomic drag to the summit. It has enough variation to punish riders who pace only by the average.

The key to understanding Tera Pass is the relationship between its length and its gradient. A 23.2 km climb at this average asks for patience more than aggression. The road gains 834 m from start to summit, so the difficulty comes from accumulation. Even if much of the ascent feels manageable, the duration means small pacing errors compound. A rider who treats the early kilometres as easy free speed can arrive at the steeper ramps already over budget.

How the gradient unfolds

The available profile numbers point to a climb with a moderate overall slope interrupted by sharper sections. Since the average sits at 3.59% while the maximum reaches 10.02%, the road cannot be uniformly steep. There will be easier ground that pulls the average down, but the harder ramps are steep enough to change the effort demand quickly.

That matters tactically. On a steady climb, holding one power target usually works. On Tera Pass, the better approach is to let effort rise slightly on the steepest pitches without chasing speed, then settle immediately when the road eases. The climb rewards smoothness: stay below panic effort on the double-digit ramps and use the gentler sections to restore rhythm rather than to attack the climb again.

Pacing and gearing notes

Start conservatively. The bottom begins already high at 2060 m, and the summit sits at 2894 m, so the climb is not just long, it is sustained at elevation. Even without needing to overcomplicate the physiology, that argues for controlled pacing from the first kilometre.

A useful strategy is:

• Ride the opening section under control, even if the gradient feels modest.
• Keep pressure steady through the middle of the climb, using perceived effort alongside power.
• On ramps near the 10.02% maximum, shift early and protect cadence rather than forcing a big gear.
• Save any real acceleration for the final part only if breathing and leg tension still feel stable.

For gearing, choose a setup with a true low climbing gear. The average gradient may suggest standard climbing gearing is enough, but the maximum gradient says otherwise. A low gear gives you room to stay seated, keep traction, and avoid spiking above sustainable effort. If riding by power, anchor the effort around your known climbing range rather than the average gradient alone. See /glossary/ftp if you use threshold to structure pacing.

The practical takeaway is simple: Tera Pass is not defined by one brutal wall. It is defined by length, altitude gain, and intermittent steepness. Respect the 23.2 km first, manage the 10.02% ramps second, and the climb becomes a pacing problem rather than a survival test.
