Dead Indian Pass cycling climb profile
Dead Indian Pass is a Category 1 climb in the US that asks a fairly simple question: can you stay disciplined for a long time when the gradient rarely needs to be dramatic to do damage?
The headline numbers explain the character of the climb. It runs for 27.5 km, starts at 1411 m, and tops out at 2462 m, with 1051 m of net elevation gain. The average gradient is 3.82%, while the maximum gradient is 7.58%. That gap between the average and the steepest pitch matters. This is not a climb that looks brutal because of one savage wall. It is a climb that accumulates fatigue through length, altitude gain, and repeated time spent applying pressure.
How the gradient rides
On paper, the 3.82% average makes Dead Indian Pass look manageable, but that number can be misleading if it encourages you to ride it like a tempo drag. Over 27.5 km, even a moderate gradient becomes a real aerobic commitment. The maximum gradient of 7.58% tells you there are steeper sections capable of breaking rhythm, but not the kind of pitch that should force a survival effort if you have chosen the right gear.
The practical takeaway is that the climb should be ridden as a long threshold-adjacent effort only if you are specifically targeting a hard ascent. For most riders, the better approach is controlled endurance climbing: settle early, avoid chasing speed changes, and leave enough margin to handle the steeper ramps without spiking power.
Pacing and gearing notes
Because the climb gains 1051 m from start to summit, the cost of early impatience is high. A strong start can feel cheap at 3.82%, but the duration means small over-pacing errors compound. If you ride by power, anchor the lower slopes below your target ceiling rather than trying to average your goal from the first minutes. If you ride by feel, breathing should stay controlled enough that the steeper sections do not immediately push you into recovery debt.
Gearing should be chosen for cadence stability, not just for the average gradient. The 7.58% maximum is not extreme, but after a long approach it can feel materially harder. Use a climbing setup that lets you stay seated and keep pressure smooth when the road steepens. Grinding the harder ramps may not cost much once, but repeated low-cadence surges on a 27.5 km climb are exactly how a moderate profile turns into a late-climb fade.
For pacing reference, this is a climb where knowing your sustainable effort matters more than chasing momentary speed. If you need to calibrate that before riding it, start with /glossary/ftp or estimate your current benchmark with /tools/ftp-estimator.
