Alto de Velefique

Overview

Alto de Velefique is a Hors Catégorie (HC) climb in Spain, rising 10.6 km from a start elevation of 762 m to a summit at 1,791 m. Over that distance it delivers a net elevation gain of 1,029 m at an average gradient of 9.75%, which places it firmly among the hardest paved ascents you can ride. There is no easing into this one: the average alone tells you the road tips upward and stays there.

The number that reshapes how you should think about the effort is total ascent. You climb 1,367 m of vertical to gain 1,029 m net, meaning roughly 338 m of that work is spent re-climbing ground lost to descents and dips along the way. That undulation matters. Every short drop breaks your rhythm and forces you to rebuild momentum, so the climb feels punchier and less metronomic than a clean 9.75% grade would suggest.

How the Gradient Unfolds

An average of 9.75% hides real variance. On a climb with 338 m of extra ascent baked in, the road is not a uniform ramp — it stacks steep pitches against brief recoveries, and the steepest sections run well above the average. Ride the average and the ramps will still hurt; ride the ramps and the flatter bits become genuine rest.

• Short recovery or flatter sections where the road dips before rising again
• Repeated short climbs that reset your cadence and cost momentum
• The steepest ramp reaching a maximum gradient of 38.87%, far above the 9.75% average

Pacing Notes

On an undulating HC climb, chase even effort, not even speed. Your pace will swing with the grade, and that is correct — hold a steady sustainable power output rather than a fixed km-per-hour target. Fighting to keep speed constant over the steep ramps burns matches you cannot replace across 10.6 km and 1,367 m of ascent.

Know your ceiling before you start. Use the FTP estimator to set a realistic target, then ride just below it on the average pitches and accept the surges over the steepest sections without redlining.

Gearing

The 38.87% maximum gradient dictates your setup. Bring a compact or sub-compact chainset paired with a wide-range cassette — a 34×32 or 34×34 at minimum — so you can keep the pedals turning on the steep ramps instead of grinding to a stall. Check your drivetrain before the ride: confirm the cassette and chainring actually give you the low gear you expect, because there is no bailout on a wall this steep.

Summary

• Length: 10.6 km
• Average gradient: 9.75%
• Maximum gradient: 38.87%
• Net elevation gain: 1,029 m
• Total ascent: 1,367 m
• Category: HC

Alto de Velefique rewards discipline. Pace to power, gear for the steepest ramp, and treat the undulation as the defining challenge rather than a footnote. Get those three right and the 1,029 m of net gain becomes a hard day well ridden rather than a blow-up waiting to happen.
