Cordova Pass

Overview

Cordova Pass is a Category 1 climb in the United States, running 26.4 km from a start elevation of 2,336 m up to a summit of 3,427 m. Over that distance it delivers a net elevation gain of 1,091 m at an average gradient of 4.13%. On paper that average reads as moderate, but a Category 1 rating over this length signals a sustained effort at real altitude, where the thin air near the top adds a tax no gradient figure captures.

The number worth studying is the gap between net gain and total ascent. You climb 1,091 m net, but the road actually accumulates 1,581 m of ascent. That 490 m difference means the route gives back roughly 490 m of descent along the way, so you are pedaling uphill considerably more than the net figure implies. Every meter you coast down has to be re-climbed, and those repeated re-ascents are where an "easy 4%" quietly turns into a hard day.

How the Gradient Unfolds

The 4.13% average is diluted by the descending and flatter sections baked into that 1,581 m of total ascent. Real pitches run steeper than the average suggests, with the sharpest ramp hitting 15.92% — more than triple the mean. Expect the effort to arrive in pulses rather than one steady drag.

• Flatter and recovery sections where the road briefly descends or eases, dropping you back toward the net-gain line
• Repeated short climbs that rebuild the elevation lost on each dip
• A steepest ramp at 15.92% that will spike your power and force a gear change

Pacing Notes

On an undulating climb like this, chasing an even speed is a trap: holding the same pace up the 15.92% ramp as on the flatter stretches will blow you apart. Pace to even effort instead. Anchor your target to a sustainable power output you can hold for the full 26.4 km, let your speed rise on the shallow and descending sections, and accept a slower crawl on the steep pitches while keeping wattage in check. If you do not know your ceiling, run the numbers through the FTP estimator before committing to a target. At this altitude, err conservative — the summit at 3,427 m will punish an over-cooked first half.

Gearing

The steepest gradient governs your setup, and 15.92% demands low gearing. Fit a compact (34-tooth inner) or sub-compact chainset paired with a wide-range cassette — a 34×32 or 34×34 gives you the spin-friendly bailout ratio you want when the road kicks up. That low gear also protects your legs on the repeated re-ascents, where grinding a big gear compounds fatigue. Check your chainset and cassette before the ride; discovering you are under-geared at 3,000 m with no easier gear left is a mistake you make only once.

Summary

• Length: 26.4 km
• Average gradient: 4.13%
• Maximum gradient: 15.92%
• Net elevation gain: 1,091 m
• Total ascent: 1,581 m
• Category: 1

Cordova Pass rewards riders who respect the gap between its gentle average and its real workload. Pace to effort, gear low, and let the 490 m of hidden re-climbing dictate your patience rather than your ego.
