Anta Dhura Pass

Anta Dhura Pass cycling climb profile

Anta Dhura Pass is not a climb to judge by average gradient alone. On paper, 91.1 km at 3.97% looks manageable if read like a steady Alpine road. The problem is that this average is stretched across a very long route, with 3,848 m of total ascent and a summit at 5,484 m. That combination changes the ride completely. This is an endurance climb first, a pacing test second, and a gradient-management problem whenever the road rears up.

The start sits at 1,872 m, so the climb begins already high enough that careless early pacing can become expensive later. The net elevation gain to the summit is 3,612 m, while total ascent is higher at 3,848 m. That tells you the road is not a simple, uninterrupted ramp. There are likely easing sections, rollovers, or small losses of height hidden inside the profile. Those sections matter because they can trick riders into either over-recovering and losing rhythm, or pushing too hard because the average gradient feels modest.

How the gradient unfolds

The headline gradient is 3.97%, but the maximum gradient is 21.81%, and that is the key tactical detail. A climb with this length and that kind of maximum pitch is rarely about holding one smooth tempo from bottom to top. The average says there is a lot of riding below the steepest ramps. The maximum says the climb has sections where gearing and torque become decisive.

That contrast should shape the whole approach. The lower and middle portions need to be ridden with restraint, not because they are necessarily steep throughout, but because the total work is enormous. Burning matches early on a climb that gains 3,612 m before topping out at 5,484 m is a poor trade. Any steep ramp later will punish the rider who has already turned the climb into a threshold effort.

Pacing strategy

Treat Anta Dhura Pass as a long aerobic effort with repeated checks against ego. The right intensity is one that feels almost too controlled early, especially if the gradient is sitting near or below the average. Use the easier terrain to keep pressure on the pedals without chasing speed. The important metric is durability, not early pace.

If riding by power, this is a climb where staying below your sustainable climbing ceiling matters more than matching a target number every minute. A short pitch at 21.81% can force power above plan even in the easiest gear, so the surrounding kilometres need to be conservative. For riders using /glossary/ftp as a reference, the sensible move is to leave enough headroom that the steepest ramps do not turn into repeated anaerobic efforts.

Gearing and ride execution

Choose gearing for the maximum gradient, not the average. A setup that feels fine on 3.97% can become unrideable when the road touches 21.81%, especially after hours of climbing and at a summit elevation of 5,484 m. A low climbing gear is not a bailout here. It is the tool that lets you keep cadence, reduce muscular strain, and avoid spiking effort on the hardest ramps.

The best ride is patient and deliberately uneventful. Keep cadence comfortable on the steadier sections, shift early before the steepest pitches, and avoid forcing a big gear just to preserve speed. On a climb this long, the rider who manages the easy kilometres properly is the rider most likely to still have control when the profile finally shows its teeth.
