Port de Morella

Overview

Port de Morella is a category 2 climb that stretches for 10.5 km at an average gradient of 5.23%. It begins at 700 m and tops out at 1250 m, giving a net elevation gain of 550 m. Its recorded total ascent of 518 m tells you the road isn't a flawless upward ribbon — there are shallow reliefs and false flats folded into the profile that soften the raw numbers slightly. On paper, a sub-6% average sounds gentle. In the legs, a spike to 15.14% at its steepest point reminds you that averages hide the real story.

How the Gradient Unfolds

The tension of this climb lies in the gap between its 5.23% average and its 15.14% maximum. That is nearly a threefold difference, and it means the effort is anything but uniform. Long stretches will sit comfortably below the average — the kind of grade where you can settle into a rhythm and breathe — punctuated by pitches that lurch well into the double digits. The fact that total ascent (518 m) sits below net gain (550 m) confirms the presence of brief flatter or recovering sections where the road eases before biting again. Treat the mellow kilometres as recovery banked against the steep ramp, not as free speed to burn.

Pacing Notes

Because the gradient is so uneven, pacing by feel alone will burn matches on the steep pitches. Anchor your effort to your FTP instead. Over 10.5 km, most riders will spend somewhere between forty minutes and an hour climbing, which places the sustainable target near or just below threshold. On the shallow sections hold steady, and on the 15.14% ramp accept that power will surge above target for a short burst rather than trying to hold a fixed speed. If you don't know your threshold yet, run the numbers through the FTP estimator before your next attempt so your pacing has a real anchor. The 550 m of vertical is entirely manageable if you meter the early kilometres and arrive at the steep section with something in reserve.

Gearing

The average gradient of 5.23% is friendly enough on almost any setup, but the 15.14% maximum is what should decide your cassette. On that ramp, a shortfall of gears turns a rhythmic climb into a grinding survival crawl. A compact chainring paired with a wide-range cassette is the sensible baseline. Strong riders on fresh legs can manage a 34×32, which keeps cadence workable across most of the climb. If you're carrying fatigue, riding at altitude, or simply prefer to spin, step up to a 34×34 for that extra margin on the steepest pitch. Over 10.5 km, protecting your cadence is worth far more than saving a few grams.

Summary

Port de Morella rewards patience and punishes over-enthusiasm on its opening kilometres. Respect the 15.14% ramp, pace to your threshold, and carry gearing that lets you spin rather than grind, and the 550 m of climbing becomes a satisfying category 2 effort rather than a struggle.
