Marmot Pass

Overview

Marmot Pass is a Category 1 climb in the US, running 7.7km from a start elevation of 787m to a summit at 1355m. That works out to a net elevation gain of 568m over the course of the ascent, a sustained effort that puts it firmly in the harder end of the categorized-climb spectrum. It is long enough to demand real pacing discipline and steep enough that you cannot simply muscle over it.

The gap between the net elevation gain of 568m and the total ascent of 632m is the detail worth flagging. Those 64 metres of extra climbing mean the road gives some elevation back before taking it again — this is not a single clean drag upward. Every metre you descend or coast is a metre you have to re-earn, so the effort is punchier and less rhythmic than the average gradient alone would suggest.

How the Gradient Unfolds

The 7.39% average gradient is a blended figure that hides both the recovery breaks and the walls. With 64m of give-back folded into the profile, the true climbing sections are steeper than the average implies, because flatter and downhill stretches drag the mean down.

• Flatter or recovery sections where the road eases and undulation gives back elevation
• Repeated short climbs that reset your rhythm rather than one continuous grind
• Steeper ramps well above the 7.39% average, where the real work concentrates

Read the road ahead rather than the number on your head unit — the average will lie to you on both the easy and hard sections.

Pacing Notes

On an undulating climb like this, chase even effort, not even speed. Holding a steady pace over the flatter recovery sections wastes energy you will need on the ramps, while grinding a fixed speed up the steep pitches spikes you into the red. Anchor your pacing to a sustainable power output and let your speed rise and fall with the terrain. Push slightly under threshold on the steep ramps and soft-pedal the recoveries to bank effort. If you do not know your ceiling, run the FTP estimator before you commit to a number, because the 64m of undulation punishes anyone who guesses too high early.

Gearing

Gear for the steepest ramps, not the average. On a Category 1 climb of this length and pitch, fit a compact (50/34) or sub-compact chainset paired with a wide-range cassette — an 11-32 or 11-34 giving you a 34×32 or 34×34 bailout gear. That low ratio lets you spin the steep sections instead of stalling and blowing up. Check your setup before the ride: confirm the cassette and derailleur can actually handle the range, and that your rear mech has the capacity for it.

Summary

• Length: 7.7km
• Average gradient: 7.39%
• Net elevation gain: 568m
• Total ascent: 632m
• Category: 1

Marmot Pass rewards riders who pace to effort and gear conservatively. Respect the 64m of undulation baked into that 632m of total ascent, hold a sustainable output, and the 568m of net gain becomes a climb you finish strong rather than survive.
