Colle di Balestrino

Overview

Colle di Balestrino is a Category 2 climb in Italy that runs 12.6 km from near sea level into the hills above the Ligurian coast. It starts at just 2 m of elevation and tops out at 637 m, for a net elevation gain of 635 m. On paper that is a moderate, medium-length climb with an average gradient of 5.06%.

The average, however, understates the work. The climb records 1,214 m of total ascent against only 635 m of net gain. That 579 m gap means the road repeatedly rises and falls rather than climbing cleanly. You pay for every descent by re-climbing what you gave back, so the effort is closer to a climb of nearly double the net gain. Expect a rhythm-breaking profile, not a steady drag.

How the Gradient Unfolds

A 5.06% average on an undulating road tells you almost nothing about any given kilometre. Because the climb loses and regains hundreds of metres, the gradient swings from flat or downhill to sharply positive. The climbing sections are steeper than the average implies, since the descents drag the mean down.

• Flatter and recovery sections where the road levels or drops, letting you spin
• Repeated short climbs stacked back to back rather than one continuous grade
• The steepest ramps punching well above the average, where you shift down and grind

Read the road ahead and treat each rise as its own effort.

Pacing Notes

On a clean climb you would hold even effort and let speed vary. Here the undulation makes pure even-effort pacing awkward: you would burn matches cresting every rise and then coast the descents. Instead, anchor your hard sections just below your sustainable power output, ease genuinely on the descents and flats to recover, and avoid surging over each crest. Even-speed pacing is a trap on this profile because holding speed uphill means spiking power. If you do not know your ceiling yet, run the FTP estimator first and pace to numbers.

Gearing

The steep ramps on this climb govern your setup, not the gentle average. Fit a compact or sub-compact chainset paired with a wide-range cassette so you always have a bailout gear for the steepest pitches. A 34×32 or 34×34 low keeps your cadence up when the road kicks, sparing your legs across the repeated climbs. Check your chainrings and cassette before the ride, not at the base of the first ramp.

Summary

• Length: 12.6 km
• Average gradient: 5.06%
• Net elevation gain: 635 m
• Total ascent: 1,214 m
• Category: 2

Colle di Balestrino is a deceptive Category 2 climb: a modest average gradient masks 1,214 m of total climbing across a rolling profile. Pace the ramps, recover on the descents, and bring gearing that respects the steep pitches rather than the mild mean.
