Cochetopa Pass

Overview

Cochetopa Pass is a category 3 climb in the United States, running 5.7 km from a start elevation of 2799 m to a summit at 3083 m. Over that distance it delivers a net elevation gain of 284 m at an average gradient of 4.99%. On paper that is a moderate, mid-length effort at real altitude, the kind of climb where the thin air matters as much as the slope.

The number that reshapes the effort is the gap between net gain and total ascent. You climb 284 m in net terms, but your legs actually do 436 m of ascending — an extra 152 m spread across the profile. That surplus comes from undulation: the road repeatedly dips and lifts, so you give back roughly 152 m of descent and reclaim it. Expect an effort that feels harder than a steady 284 m drag, because every dip breaks your rhythm and forces you to rebuild speed.

How the Gradient Unfolds

The 4.99% average is a blend, not a constant. With a maximum gradient of 12.8%, the steep pitches sit well above the mean, and the flatter and descending sections pull the average back down. Ride to the average and you will be over-geared on the ramps and coasting through the dips.

• Flatter and false-flat recovery sections where the gradient drops below average — use them to eat, drink, and reset breathing.
• Short descents that erase some of your climbing, contributing to the 436 m total ascent — carry momentum into the next rise.
• Repeated short climbs between the dips, each demanding a fresh surge of effort.
• The steepest ramp at 12.8%, roughly two and a half times the average — the pitch that dictates your gearing.

Pacing Notes

On an undulating climb like this, even-effort beats even-speed. Chasing a constant speed forces you to spike hard over every rise and soft-pedal every dip, spiking your sustainable power output and burning matches you will want later. Instead, hold steady effort: let speed climb on the descents and fall on the ramps while your output stays honest.

At 2799 to 3083 m, altitude trims the power you can hold, so pace conservatively off the front. Run the FTP estimator first, then ride the ramps just under threshold and use the recovery sections to bring your average heart rate back down.

Gearing

The 12.8% maximum governs your setup. At that grade, after nearly 3000 m of thin air, you want a compact (50/34) or sub-compact chainset paired with a wide-range cassette — a 34×32 or 34×34 gives you a spinnable bailout on the steepest ramp without cross-chaining. Check your setup before the ride: confirm the cassette and derailleur capacity handle your largest sprocket, and that the rear mech shifts cleanly under load.

Summary

• Length: 5.7 km
• Average gradient: 4.99%
• Maximum gradient: 12.8%
• Net elevation gain: 284 m
• Total ascent: 436 m
• Category: 3

Cochetopa Pass rewards riders who respect the undulation and the altitude. Gear for the 12.8% ramp, pace by effort rather than speed, and treat the extra 152 m of ascent as the true cost of the day.
