Pedrizas Pass

Overview

Pedrizas Pass is a Category 3 climb in Spain, running 6.8 km from base to summit. Starting at 494 m elevation, it gains 303 m net to reach a summit at 797 m. The total ascent of 440 m — notably higher than the net gain — tells you the road isn't a clean, uninterrupted ramp. There are undulations along the way, meaning you'll surrender some hard-earned altitude before the final push.

The average gradient of 4.46% keeps this squarely in the accessible range for most trained cyclists, but the 12.21% maximum gradient is a reminder not to treat the whole climb as a casual tempo effort.

How the Gradient Unfolds

With a 37 m gap between net elevation gain (303 m) and total ascent (440 m), expect at least one notable dip mid-climb where the road flattens or briefly descends before resuming the ascent. This is both a mental and physical feature:

• Lower slopes: At an average just under 4.5%, the opening kilometres invite you to find a rhythm. Resist the temptation to push hard here — the 12.21% ramp is somewhere ahead.
• Mid-section undulations: Where the road dips, use the recovery but stay loose and keep cadence up. Don't coast through it entirely; maintain momentum.
• Upper ramp: The maximum gradient of 12.21% is steep enough to stall a poorly chosen gear. This is where overpacing the lower slopes costs you.

Pacing Notes

At 6.8 km and 4.46% average, Pedrizas Pass sits in a zone where many riders misjudge effort — it feels easy enough that early pacing discipline erodes. Keep these points in mind:

• Target a sustainable power output from the base, not one dictated by how the shallow lower gradient feels. Reference your FTP and aim for the upper end of your climbing zone, not above it.
• The undulating profile inflates total ascent. You're not climbing a steady ramp — the legs accumulate more work than the 303 m net figure suggests. Factor this in on longer ride days.
• On the steepest pitch (12.21%): If you've paced sensibly, you should be able to maintain rhythm. If you've gone too hard early, this section becomes a grind. A cadence drop below 70 rpm here is a sign you needed an easier gear or a slower approach.

Gearing Recommendations

For a climb averaging 4.46% with a 12.21% maximum, a compact chainset (50/34) or a mid-compact (52/36) will handle the majority of riders comfortably. Key considerations:

• Cassette: A 28t or 30t largest sprocket is advisable. The maximum gradient is short-lived but sharp — having the gear costs nothing and saves you on tired legs.
• Heavier riders or those later in a long ride should lean toward a 32t. The overall length is short, but the undulations mean you won't get continuous recovery.
• Lighter, stronger climbers can manage a standard 53/39 setup, but the 12.21% section will feel noticeably harder without the bail-out gear.

Practical Summary

Pedrizas Pass is a Category 3 climb that rewards composed, even-effort riding over those who attack from the base. The moderate average gradient masks a route with real bite at its steepest point.
