Manzanal mountain pass

Overview

Manzanal mountain pass is a Category 3 climb in Spain, running 9.5 km from a start elevation of 903 m to a summit of 1234 m. That gives a net elevation gain of 331 m at an average gradient of 3.48% — numbers that read like a steady, moderate haul on paper. It is the kind of climb that rewards riders who bring a plan rather than raw ambition.

The average, though, hides the real shape of the effort. While the net gain is 331 m, the total ascent is 488 m — 157 m of extra climbing you pay for in dips and re-climbs along the way. That undulation means you cannot simply lock into one gear and grind. Every descent you enjoy is elevation you have to earn back, and those repeated transitions cost more than a single sustained slope of the same net gain would.

How the Gradient Unfolds

A 3.48% average is misleading here. The undulating profile means long stretches sit below that figure while short pitches spike well above it, culminating in a maximum gradient of 14.34% — steep enough to force a hard gear change if you are caught flat-footed.

• Flatter and recovery sections where the road eases or dips, letting the average fall below 3.48%
• Repeated short climbs that stack up the 488 m of total ascent well beyond the 331 m net gain
• A steepest ramp at 14.34% — brief but sharp, and the one pitch that dictates your gearing

Pacing Notes

On an undulating climb like this, chase even effort, not even speed. Holding a constant pace forces you to over-spend on every ramp and coast through the recovery sections where the road gives back — exactly backwards. Instead, anchor your work to a target power around your sustainable power output: ease slightly on the steep pitches so you never blow past threshold, and keep pressure on the flatter and downhill segments where speed is cheap.

If you do not know that number, run the numbers through the FTP estimator before you ride so your target on the 14.34% ramp is grounded rather than guessed.

Gearing

The 14.34% maximum gradient governs your setup. A compact (34-tooth inner) or sub-compact chainset paired with a wide-range cassette gives you room to spin the steep pitch without grinding to a stall. A 34×32 is the sensible floor here; a 34×34 buys extra margin on tired legs. Check your chainset and cassette before the ride — arriving at the steepest ramp under-geared turns a manageable Category 3 into a survival effort.

Summary

• Length: 9.5 km
• Average gradient: 3.48%
• Maximum gradient: 14.34%
• Net elevation gain: 331 m
• Total ascent: 488 m
• Category: 3

Manzanal is a moderate climb with a sting in its undulation: 157 m of climbing you pay for beyond the net gain. Pace it on effort, gear it for the 14.34% ramp, and it stays within reach.
