The climb
Gradient profile
Rawil Pass cycling climb profile
Rawil Pass is not a climb to judge by its average alone. On paper, 25.4 km at 7.6% already puts it firmly in HC territory, but the more important number is the vertical gain: 1,928 m from a start elevation of 496 m to a summit elevation of 2,424 m. That means this is a long, sustained altitude gain rather than a short climb with one violent wall.
The total ascent is 1,974 m, only slightly above the net elevation gain, which tells you the route is mostly committed to going up. There is not much statistical evidence of major relief through descents or long rolling interruptions. In practical terms, this is the kind of climb where small pacing errors compound because the road keeps asking for work.
How the gradient unfolds
With only the headline profile available, the safest reading is that Rawil Pass is defined by sustained climbing pressure with sharper ramps layered into it. The 7.6% average is hard enough over 25.4 km to make threshold pacing risky for most riders, while the 21.04% maximum gradient changes the gearing requirement entirely.
That maximum does not mean the whole climb rides like a wall. It means the climb contains sections steep enough to punish anyone who arrives overgeared or already above sustainable effort. A climb can feel manageable at its average gradient, then become very different when a short ramp forces a power spike. On Rawil Pass, the smart assumption is that the steepest pitches are decisive because they arrive inside an already long effort, not because they are isolated.
Pacing and gearing notes
The core mistake here is riding the lower slopes as if the average gradient is the whole story. A 25.4 km climb with 1,928 m of net gain rewards patience. Keep the early effort controlled, especially if riding by /glossary/ftp, because the cost of repeated surges will show up later when the road steepens or the altitude rises toward 2,424 m.
Gearing should be chosen for the 21.04% maximum, not the 7.6% average. If your easiest gear only feels comfortable on steady mid-single to high-single digit gradients, it may be too ambitious for this climb. The aim is not just to get over the steepest ramps, but to get over them without having to grind at a cadence that spikes muscular fatigue.
Practical takeaway
Rawil Pass is a sustained HC ascent with enough maximum gradient to demand conservative execution. Ride it as a long aerobic climb first, then treat the steep ramps as sections to manage rather than attack. The riders who handle it best will be those who keep pressure steady, avoid early surges, and arrive at the upper slopes with enough cadence range left to stay in control.
