Passo dei Ghiffi

Overview

Passo dei Ghiffi is a category 1 climb that asks a serious question over its full 15.7 km. From a start elevation of just 60 m, the road works its way up to a 1058 m summit, a net gain of 998 m. The average gradient of 6.36% sounds civil enough on paper, but averages hide the truth on a climb this long: a total ascent of 986 m packed into a sustained effort means very little of it is flat, and the ramps that spike toward the 16.57% maximum will test even strong legs. This is a climb you settle into, not one you attack from the bottom.

How the Gradient Unfolds

The shape here is defined by consistency punctuated by cruelty. At 6.36% average across 15.7 km, the climb never really releases you — there are no long false flats to recover on and no meaningful descents to break the rhythm. The gap between the 6.36% average and the 16.57% maximum tells you where the danger lives: short, sharp pitches roughly ten points steeper than the mean. These are the sections that shatter a tempo effort. Between them, the road hovers close to the average, a relentless grade that slowly banks elevation. Over 15.7 km you gain 998 m net, so the overall trend is a steady upward drag with the occasional lurch toward the steep.

Pacing Notes

The mistake on Passo dei Ghiffi is going out too hard on the friendlier lower gradients. With 15.7 km ahead, discipline pays. Anchor your effort to your FTP and aim to hold a sustainable power just below threshold on the steady sections, keeping something in reserve for the 16.57% ramps where you will naturally spike. If you do not know your threshold, run the numbers first with the FTP estimator so you climb to a target rather than to feel. On the steepest pitches, accept that speed will drop — protect your effort, not your pace, and let the grade dictate a lower cadence rather than blowing your FTP to chase a number.

Gearing

For a 15.7 km climb averaging 6.36% with pitches to 16.57%, gearing is not a place to be brave. A compact 34-tooth inner ring paired with a 32-tooth cassette sprocket (34×32) is the sensible minimum for most riders, giving you a spinnable gear on the sustained grade. But given the 16.57% maximum, going one step easier to 34×34 buys real insurance — that extra rear tooth is the difference between spinning over the steepest ramps and grinding to a stall. If you climb seated and value cadence, or you are riding this at the end of a long day, take the 34×34 and enjoy the margin.

Summary

Passo dei Ghiffi rewards patience: a long, steady category 1 climb with just enough steep to punish the impatient. Pace to your threshold, gear for the ramps, and let the 15.7 km come to you.
