Passo del Maloja/Aira da la Palza

Overview

Passo del Maloja/Aira da la Palza is a long, category 1 haul that rewards patience over punch. Over 17.1 km it climbs at an average of 5.94%, lifting you from a start elevation of 803 m to a summit of 1820 m. That works out to a net gain of 1017 m, with total ascent measured at 999 m — the small difference between the two tells you the profile isn't a single unbroken wall but includes brief levelling or dips where you can breathe. The headline number to respect is the 15.1% maximum gradient, a slope more than twice the average that will find any weakness in your legs or your gearing.

How the Gradient Unfolds

Read the two elevation figures together and the shape comes into focus. A net gain of 1017 m against a total ascent of 999 m means the road mostly points up but hands back a little altitude along the way — enough downhill or flat to matter for rhythm, not enough to give you a real rest. A 5.94% average across 17.1 km is a climb you settle into rather than attack; the danger is the 15.1% max, roughly two and a half times steeper than the mean, which means the effort is uneven. Expect long stretches near the average that lull you into a comfortable cadence, then a ramp toward that 15.1% figure that forces a hard, sudden gear change. Meter it out: the 1017 m of total lift is what your legs actually pay for, top to bottom.

Pacing Notes

On a climb of this length, discipline beats bravado. Aim to hold an even effort around your threshold rather than chasing the gradient — surging on the easy sections and blowing up on the steep ones is the classic way to lose time here. Anchor your pacing to your FTP and try to sit just below it for most of the 17.1 km, keeping a small reserve for the pitches approaching 15.1%. If you don't know your current number, run it through the FTP estimator before you ride so your power targets reflect today's form. With a net gain of 1017 m to absorb, going out too hard in the first few kilometres is the single most expensive mistake you can make.

Gearing

Given the 5.94% average and, more importantly, the 15.1% max, don't under-gear this one. A compact 34-tooth inner chainring paired with a 34×32 low is the sensible baseline for most riders who want to spin rather than grind the steep sections. If you're carrying fatigue, riding at altitude near the 1820 m summit, or simply prefer a lighter cadence, step down to a 34×34 for extra insurance on the ramps toward 15.1%. Over 17.1 km, protecting your cadence early keeps your legs alive for the top.

Summary

Passo del Maloja/Aira da la Palza is a long category 1 test defined by its length and a stinging 15.1% high point rather than a relentless average. Pace it evenly, gear it generously, and the 1017 m of net gain becomes manageable.
