Guadalupe Pass (Texas)

Overview

Guadalupe Pass is a Category 3 climb in West Texas, US, running 8.7 km from base to summit. It gains 358 m net, starting at 1,294 m and topping out at 1,652 m of elevation. This is a mid-length effort with a moderate overall pitch, the kind of climb that rewards steady riders over pure punchers.

The total ascent on this climb is 384 m, which is 26 m more than the 358 m net gain. That difference comes from short descents and dips along the way that you have to climb back out of. It is a small undulation, but it means the road does not rise in a single clean line. Expect brief downhill or flat moments that break your rhythm, then reload the effort each time the grade tips back up.

How the Gradient Unfolds

The 4.13% average is a useful summary but a poor guide to how the climb actually feels. With 26 m of undulation baked into the profile, the real gradient swings above and below that mean. The steepest measured pitch reaches 9.74%, more than double the average, so the hardest metres are concentrated rather than spread evenly.

• Flatter and recovery sections where the road eases below average, often right after a short dip
• Repeated short climbs as you re-ascend the small descents, each demanding a fresh surge
• The steepest ramp near 9.74%, the single hardest stretch and the one to plan your gearing around

Pacing Notes

On an undulating climb like this, chase even effort, not even speed. Hold a steady sustainable power output through the ramps and let your speed rise on the flatter recovery sections rather than pushing to keep pace constant. Surging over every rise to defend a target speed burns matches you will want back at the 9.74% pitch.

If you do not know your numbers, run the FTP estimator first, then set a ceiling you can hold for the full 8.7 km. The dips are your chance to soft-pedal and recover, not to attack.

Gearing

Gear for the steepest gradient, not the average. A near-10% ramp on a climb of this length calls for a compact or sub-compact chainset paired with a wide-range cassette, something like a 34×32 or 34×34, so you can hold cadence when the grade bites without grinding.

Check your setup before the ride. Confirm your smallest chainring and largest sprocket give you a bailout gear for the 9.74% section, and that the drivetrain shifts cleanly under load. Fixing gearing at the trailhead is not an option.

Summary

• Length: 8.7 km
• Average gradient: 4.13%
• Maximum gradient: 9.74%
• Net elevation gain: 358 m
• Total ascent: 384 m
• Category: 3

Guadalupe Pass is an honest Category 3 test: long enough to matter, gentle enough on average to pace well, but with a steep pitch and mild undulation that punish riders who go out too hard. Manage your effort, gear for the ramp, and it rides well.
