Colle della Mologna Grande

Colle della Mologna Grande cycling climb profile

Colle della Mologna Grande is a category 1 climb in Italy built around duration rather than a single headline wall. The numbers set the tone clearly: 22 km at an average gradient of 5.55%, starting at 316 m and topping out at 1538 m. That gives the climb its main difficulty. It is long enough that pacing errors made early can sit in the legs for a long time, but the average gradient is not so high that the whole ascent forces a survival rhythm from the first pedal stroke.

The important tactical detail is the gap between the average gradient and the maximum gradient. A 5.55% average across 22 km suggests a climb that can be ridden aerobically for large stretches, but the listed maximum of 19.39% changes how it should be approached. This is not a climb to treat as a flat power test at one steady output. The steepest sections are severe enough to force cadence down, spike torque, and punish anyone riding too close to threshold before they arrive.

How the gradient unfolds

With only the headline profile available, the safest reading is simple: the climb gains its damage through accumulation, then asks for repeated discipline when the road steepens. The ascent rises from 316 m to 1538 m, so the vertical gain is substantial, and the full 22 km length means the gradient does not need to be constantly extreme to become selective.

The average tells you the climb has many rideable sections. The maximum tells you there are ramps where gearing and pacing matter more than ego. That combination usually rewards riders who keep the early and middle parts controlled, rather than those who try to make every moderate section feel productive. If the road eases, use it to settle back into rhythm. If it pitches up, accept a lower cadence or a short power rise, but avoid turning every steep ramp into a maximal effort.

Pacing and gearing notes

The right approach is to ride the first part below your limit, especially if you are pacing by /glossary/ftp. On a 22 km climb, the cost of going too hard early is not just local fatigue. It reduces your ability to handle the steepest ramps later, where the 19.39% maximum gradient can force high muscular load even at modest speed.

Practical setup should favour range. A compact or climbing-friendly gear is the safer choice because the maximum gradient is far above the average. If you gear only for 5.55%, the steep ramps can turn into low-cadence grinding, which is exactly where fatigue compounds fastest on a long climb.

A good pacing model is:

• Settle into a sustainable tempo early and ignore short-term speed.
• Keep pressure smooth on moderate gradients, rather than chasing time.
• Save enough capacity for the steepest ramps, where cadence may naturally fall.
• Use any easier sections to restore breathing before the next increase in gradient.

Colle della Mologna Grande is not defined by one number. The full picture is the interaction between length, a moderate average gradient, and a very steep maximum. Ride it like a long aerobic climb with sharp interruptions, not like a steady laboratory effort.
