Coll de la Forca

Overview

Coll de la Forca is a Category 2 climb in Spain, running 8.1 km from a start elevation of 964 m to a summit at 1491 m. Its net elevation gain is 527 m, and it averages 6.5% across the ascent. On paper that is a steady middle-category effort: long enough to demand a real plan, short enough to hold a firm rhythm from base to top.

The number that reshapes the picture is total ascent. While net gain is 527 m, the climb racks up 735 m of total ascent, a difference of 208 m. That gap is undulation: the road repeatedly rises and dips rather than climbing cleanly. You pay for those 208 m of extra vertical without them showing up in the net figure, so the climb is harder than a flat 527 m/8.1 km reading suggests. Expect to spend energy you do not get back on the intervening descents.

How the Gradient Unfolds

The 6.5% average hides the real shape of the road. With 735 m of total ascent packed against a 6.5% mean, the steep sections must be balanced by genuinely flat or descending stretches. Treat the average as a bookkeeping figure, not a description of any single moment on the bike.

• Flatter or descending recovery sections where the road briefly gives elevation back
• Repeated short climbs that stack up to the 735 m total ascent
• Steeper ramps well above the 6.5% average, where the gradient bites hardest
• Little in the way of long, uniform grade — the effort comes in pulses

Pacing Notes

On an undulating climb like this, even-effort beats even-speed. Chasing a constant speed forces you to spike hard on every ramp and coast on every dip, burning matches you will want later. Instead, hold a steady sustainable power output through the climbs and let your speed rise and fall with the terrain.

Ease off on the descending sections rather than hammering to keep the clock moving — that recovery is what lets you attack the next ramp cleanly. If you do not know your ceiling, run the FTP estimator first and set a target you can actually hold across all 8.1 km and 735 m of ascent.

Gearing

The steep ramps here punish tall gearing. Fit a compact or sub-compact chainset and pair it with a wide-range cassette — 34×32 or 34×34 — so you have a bailout gear when the grade kicks well above the 6.5% average. A low bottom gear lets you spin the ramps at a sustainable cadence instead of grinding and blowing up. Check your setup before the ride; do not discover a missing gear mid-climb.

Summary

• Length: 8.1 km
• Average gradient: 6.5%
• Net elevation gain: 527 m
• Total ascent: 735 m
• Category: 2

Coll de la Forca reads as a moderate Category 2 effort, but the 208 m gap between net gain and total ascent tells the real story. Pace it by effort, gear for the steep ramps, and respect the undulation — that is where the climb is won or lost.
