Douglas Pass

Overview

Douglas Pass is a Category 2 road climb in the US, running 10.2 km from a start elevation of 1,925 m to a summit at 2,468 m. On paper it is a net gain of 543 m at an average gradient of 5.33% — a mid-tier effort that most fit riders can reach the top of without a struggle, provided they read the terrain correctly.

The number that reshapes that picture is total ascent: 947 m. Against a net gain of 543 m, that leaves roughly 404 m of climbing you do twice — pitches you crest, give back on a descent or false flat, then have to reclaim. This is not a steady grind up a single face. It is an undulating road, and the extra vertical meters are paid for in repeated changes of pace that cost more than the average gradient suggests.

How the Gradient Unfolds

An average of 5.33% is a blend, not a description. Because the profile rolls, the flatter and descending sections drag the average down, which means the climbing pitches are steeper than 5.33% wherever the road actually goes up. Expect the effort to be lumpy rather than smooth.

• Recovery zones: flatter sections and short descents where you can back off and refuel
• Repeated short climbs: several distinct ramps rather than one continuous wall
• The steepest ramp: the hardest pitch is materially steeper than the average, so keep a gear in reserve for it

Pacing Notes

On a rolling climb like this, chasing an even speed is a trap — you will overspend on every ramp and coast the descents, arriving at the summit cooked. Pace by even effort instead. Hold a steady sustainable power output on the climbs, let your speed rise on the flatter and downhill sections without hammering, and treat the recovery zones as genuine recovery.

If you do not know your ceiling, run the FTP estimator first and set a target you can hold across all 10.2 km. The undulation makes discipline matter more here than on a constant-gradient climb: the temptation to surge each ramp compounds over 947 m of total ascent.

Gearing

Gearing should be governed by the steepest ramp, not the average. Come with a compact (50/34) or sub-compact chainset paired with a wide-range cassette — a 34×32 or 34×34 low gear gives you the cadence to spin the steep pitches without grinding. Check your setup before the ride: confirm the cassette range, the rear derailleur can handle it, and shifting is clean under load. You do not want to discover you are over-geared halfway up a ramp.

Summary

• Length: 10.2 km
• Average gradient: 5.33%
• Net elevation gain: 543 m
• Total ascent: 947 m
• Category: 2

Douglas Pass is more demanding than its Category 2 rating and 5.33% average imply. The gap between 543 m of net gain and 947 m of total ascent is the whole story: pace by effort, gear for the steepest ramp, and respect the meters you climb more than once.
