Galena Summit

Overview

Galena Summit is a Category 3 climb in the United States, running 10.7 km from a start elevation of 2,214 m to a summit of 2,646 m. The net elevation gain is 432 m, and the road tops out high — this is a mountain-pass effort at altitude, where thinner air adds a tax the gradient numbers alone won't show.

The headline figure to watch is the gap between net gain and total ascent. You climb 432 m net, but the total ascent is 670 m — meaning roughly 238 m of the climb is given back and re-earned across the profile. That undulation matters: you are doing more vertical work than a simple point-to-point reading suggests, and every descent breaks your rhythm and forces you to rebuild momentum.

How the Gradient Unfolds

The 4.04% average is a blend, not a constant. With 238 m of hidden re-climbing, the road rolls rather than rises steadily, so the true working pitches are steeper than the average implies.

• Flatter and recovery sections where the road dips or levels — use them to eat, drink, and reset.
• Repeated short climbs that stack up to the 670 m total ascent, each one demanding a fresh surge of effort.
• The steepest ramp, where the gradient bites hard above the average — this is where pacing discipline pays off.

Pacing Notes

On a smooth climb, even-speed pacing works. On Galena Summit, it doesn't — the undulation punishes riders who chase a constant speed, because you'll overspend on every ramp and coast wastefully on every dip. Pace to even effort instead: hold a steady sustainable power output and let your speed rise and fall with the terrain. Ease slightly on the descents to recover, and resist the urge to hammer them back up to pace.

If you don't know your target number, run the FTP estimator before you ride and set a ceiling you can hold for the full 10.7 km — then stay under it on the steep pitches.

Gearing

Gearing here is governed by the steepest ramp, not the gentle average. At altitude, with pitches well above 4.04%, you want spinning range in reserve. 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 bailout to keep cadence up when the road kicks. Check your setup before the ride: confirm the cassette and derailleur capacity actually deliver that low gear, because the summit is no place to discover you've run out of sprockets.

Summary

• Length: 10.7 km
• Average gradient: 4.04%
• Maximum gradient: 15.81%
• Net elevation gain: 432 m
• Total ascent: 670 m
• Category: 3

Galena Summit reads as a moderate Category 3 on paper, but the 238 m gap between net gain and total ascent makes it a rhythm test at altitude. Pace to effort, gear low, and treat every dip as recovery — not a reason to sprint.
