Jaufenpass

Overview

Jaufenpass is a long category-1 test that rewards patience over aggression. Over 16.9 km it climbs from 481 m to a summit of 1435 m, a net gain of 954 m at an average gradient of 5.63%. On paper that average reads as steady tempo terrain, but the 26.88% maximum gradient tells you the road does not hold that friendly figure the whole way. This is a climb where the number that matters most is not the average — it is the spread between that 5.63% mean and the 26.88% spike. Manage that gap well and the pass unfolds smoothly beneath you.

How the Gradient Unfolds

With 954 m of net gain across 16.9 km, Jaufenpass is a genuinely long effort. The 5.63% average is the anchor you will hold for most of the ascent, but a climb rarely arrives at that mean by staying flat. The presence of a 26.88% maximum means at least one ramp sits nearly five times steeper than the average. Expect the road to breathe: shallower stretches that let you settle into a rhythm, punctuated by sharper kicks that demand a gear change and a burst of torque. The gentler sections are where you bank time and recover; the steep pitches are where the climb extracts it back. Reading the road ahead and shifting early — before the gradient bites — is the difference between spinning over a ramp and grinding to a near-standstill on it.

Pacing Notes

The smartest way to ride 16.9 km at 5.63% is to hold a steady, sustainable power target rather than chasing the fluctuations of the terrain. Anchor your effort to your FTP and aim to sit just below it on the steady sections, leaving headroom for the 26.88% ramp where power will inevitably spike. If you do not know your threshold, estimate it first with the FTP estimator, then translate that number into a climbing pace you can defend for the full 954 m of ascent. Going out too hard on the lower slopes is the classic error here — the length means any early overspend gets punished long before the summit at 1435 m.

Gearing

Gearing is what turns the 26.88% maximum from a crisis into a manageable moment. For a climb of this length and steepness, a compact 34-tooth chainring paired with a wide-range cassette is the sensible baseline. A 34×32 will get most fit riders over the steady 5.63% terrain comfortably, but on the steepest ramp it can leave you mashing a gear that is simply too big. If you have the range available, a 34×34 gives you that extra spinning gear precisely where the 26.88% pitch demands it, protecting your legs across the full 16.9 km. When in doubt, take the easier gear — you can always leave it unused.

Summary

Jaufenpass is a long, honest category-1 climb: 16.9 km, 954 m of net gain, and a 5.63% average that hides a brutal 26.88% ramp. Pace it to your threshold, gear it wide, and let the numbers do the work.
