Aceretta pass cycling climb profile
Aceretta pass is a long category 1 climb in Italy, and the key number is not the maximum gradient. It is the length. At 25.8 km with an average gradient of 4.42%, this is the type of ascent that rewards riders who can hold a controlled aerobic effort for a long time rather than riders who rely on repeated surges.
The climb starts at 396 m and tops out at 1537 m, gaining 1141 m on the road to the pass. That vertical gain spread across nearly 26 km gives the climb its character: persistent, wearing, and difficult to ride well if the pacing is loose early.
How the gradient unfolds
With a listed maximum gradient of 6.11%, Aceretta pass does not present as a climb built around violent ramps. The profile data points toward a steady ascent where the road keeps asking for pressure on the pedals, but rarely demands a full reset in rhythm.
That matters tactically. A climb averaging 4.42% can feel deceptively manageable in the opening phase, especially if the road is smooth and the effort sits just below threshold. The danger is that the low maximum gradient encourages over-pacing. Because the ascent is long, even a small early overshoot can turn the upper half into damage control.
The practical read is simple: do not chase speed. Chase steadiness. On a climb like this, the rider who keeps torque controlled and cadence stable will usually arrive stronger than the rider who treats the gradient as too gentle to respect.
Pacing strategy
Aceretta pass should be ridden as a sustained endurance-to-tempo climb unless the objective is a maximal effort. The average gradient is moderate, but the category 1 rating and 25.8 km length mean the physiological cost accumulates gradually.
For a hard ride, start below the effort you think you can hold. Let the first portion settle your breathing and cadence before moving toward a more committed pace. If using power, anchor the effort against /glossary/ftp rather than the gradient alone. The road may not force big spikes, but fatigue will still build through duration.
For training, this is well suited to long steady-state work, aerobic durability, and controlled climbing intervals where the goal is consistency rather than peak power.
Gearing notes
Because the maximum gradient is listed at 6.11%, Aceretta pass does not demand ultra-low gearing in the way a steep alpine wall would. Still, the correct setup is not about surviving one ramp. It is about preserving cadence across 25.8 km.
Choose gearing that lets you stay seated and smooth at moderate climbing speeds. If your easiest gear only feels comfortable when fresh, it is probably too ambitious for the full ascent. A compact or similarly forgiving climbing setup makes sense for most riders, not because the slope is severe, but because the climb is long enough to punish unnecessary muscular strain.
Bottom line
Aceretta pass is a climb of patience. The numbers describe a sustained, controlled ascent: 25.8 km, 4.42% average gradient, 1141 m of net gain, and no listed pitch above 6.11%. Ride it with discipline early, keep the cadence light, and treat the length as the main opponent.
