Jaufenpass - Passo di Monte Giovo

Overview

Jaufenpass, also known as Passo di Monte Giovo, is a genuine hors catégorie ascent — the hardest rating on the scale, ahead of category 1, 2, 3 and 4. Over 23 km it climbs from a valley floor at 481 m to a summit of 2107 m, a net elevation gain of 1626 m and a total ascent of 1608 m once you account for the handful of dips along the way. The average gradient of 7.08% tells only half the story: with pitches reaching 25.61%, this is a climb where the mean masks some savage individual ramps. Put simply, it is long enough to demand patience and steep enough to punish anyone who spends their matches early.

How the Gradient Unfolds

Twenty-three kilometres at 7.08% is a big block of sustained work, but the near-equal net gain (1626 m) and total ascent (1608 m) confirm this is an honest climb — it points relentlessly upward with almost no descending to reset your legs. The difference between those two figures is a mere 18 m, meaning you rarely coast. What breaks the rhythm instead are the gradient spikes. A maximum of 25.61% is more than triple the average, so expect the road to lurch well into the teens on the harder switchbacks before easing back toward the 7% baseline. Treat the average as a target and the steep ramps as brief, out-of-the-saddle events to survive rather than attack. Because the summit sits at 2107 m, thinner air near the top will make the final kilometres feel harder than their raw gradient suggests.

Pacing Notes

On a climb this long, the number that matters most is your FTP. At 23 km, most riders will be on the road for well over an hour, so pacing to a sustainable percentage of threshold — rather than chasing the steep pitches — is the difference between summiting strong and blowing up. If you do not know your threshold, run the numbers through the FTP estimator before you commit to a pace. Hold something you can defend across the full 1626 m of climbing, absorb the 25.61% ramps by shifting down and staying seated where you can, and keep a small reserve for the final, thin-air stretch to 2107 m.

Gearing

For an HC climb averaging 7.08% with ramps to 25.61%, gearing is not optional insurance — it is essential. A compact 34-tooth chainring is the starting point. Pair it with at least a 34×32 for the sustained sections, but for the 25.61% pitches near the summit a 34×34 gives you the extra range to keep cadence up rather than grinding to a near-stop. If you tend to spin rather than mash, err toward the 34×34. The goal across 23 km is to protect your legs for the top, and easier gearing keeps your effort steady over all 1626 m of ascent.

Summary

Jaufenpass is a full HC test: long, honest and topped by a genuine high-altitude finish at 2107 m. Respect the 25.61% ramps, pace to threshold, and gear low.
