Colle della Bicocca cycling climb profile
Colle della Bicocca is a category 1 climb in Italy that asks a very specific question: can you stay disciplined for a long time when the numbers look manageable on paper? At 32.2 km with an average gradient of 4.95%, it is not defined by a brutal average. It is defined by duration, accumulated fatigue, and the way a long climb can turn a moderate gradient into a pacing problem.
The climb starts at 695 m and tops out at 2286 m, giving 1591 m of net elevation gain. The total ascent is 1695 m, which matters because it tells you this is not simply one clean, steady ramp from bottom to summit. There is more climbing on the road than the net gain alone suggests, so the profile likely includes enough variation to disrupt rhythm. That difference of 104 m between total ascent and net gain is a quiet but important detail: any easing, rolling, or loss of height still has to be paid back before the summit.
How the gradient rides
The headline average of 4.95% can be misleading. Over 32.2 km, that figure implies a climb where the main challenge is not one savage wall, but the ability to keep pressure on the pedals for an extended period. The road does, however, reach a maximum gradient of 12.63%, so the climb also contains steep ramps that can punish over-gearing or poor pacing.
That combination shapes the ride. On the steadier sections, it is tempting to settle into a tempo that feels sustainable. The risk is that the longer distance and the steeper pitches later demand more freshness than expected. A climb with this much vertical gain rewards riders who leave margin early, especially because the average gradient does not tell you where the hardest ramps arrive.
Pacing and gearing notes
Treat Colle della Bicocca as an endurance climb first and a steep climb second. The correct pacing strategy is to avoid riding the lower slopes as if the average gradient makes the climb easy. If you use /glossary/ftp to anchor effort, this is the kind of ascent where a controlled sub-threshold rhythm is usually more valuable than chasing speed early.
Practical approach:
- Start conservatively, because 32.2 km is long enough for small pacing errors to compound.
- Use a gear that lets you keep cadence stable on the 4.95% average terrain without grinding.
- Save your lowest gears for the ramps approaching the 12.63% maximum, not for general climbing.
- Fuel before you feel empty, because the climb gains 1591 m net and includes 1695 m of total ascent.
The key is restraint. Colle della Bicocca is not just about surviving its steepest pitch. It is about managing the whole ascent so that when the gradient bites, you still have the torque, cadence, and metabolic headroom to ride through it rather than react to it.
