Sattel Pass

Overview

Sattel Pass is a Category 2 climb in Switzerland, running 15.1 km from a start elevation of 849 m to a summit at 1582 m. On paper it reads as a moderate ascent: the net elevation gain is 733 m, and the average gradient sits at a friendly 4.85%. That number invites you to treat it as a steady tempo effort from bottom to top.

Do not. The total ascent over those 15.1 km is 1271 m — 538 m more than the net gain. That gap is the tell. It means the road repeatedly climbs, gives some elevation back, and climbs again, so you pay for roughly 538 m of descent-and-reclaim that the summit figure never shows. The effort is materially harder than the 4.85% average suggests, because every giveback resets the momentum you built.

How the Gradient Unfolds

The 4.85% average is a blend, not a description of any single kilometer. With 1271 m of total ascent packed into a 733 m net rise, the steep pitches have to be considerably steeper than average to compensate for the flat and downhill sections. The headline number is a 23.27% maximum ramp — a wall that will force you out of the saddle regardless of how conservatively you paced the approach.

• Flatter and mild recovery sections where the road eases or tips gently downhill, giving back part of the 733 m net gain
• Repeated short climbs that each reclaim lost elevation, breaking any single sustained rhythm
• One steepest ramp at 23.27% that demands your lowest gear and a hard, brief anaerobic effort

Pacing Notes

On a smooth, consistent climb you can chase even speed. Here, even speed is a trap — holding a target pace across a 23.27% ramp would blow you apart. Pace to even effort instead, anchored to your sustainable power output. Let your speed rise on the flatter givebacks and fall on the steep pitches while your effort stays flat.

That only works if you know your ceiling. Run the FTP estimator beforehand, then ride the whole 15.1 km a touch below threshold so the repeated short climbs don't stack fatigue faster than you can clear it.

Gearing

The 23.27% maximum dictates your setup, not the 4.85% average. At that gradient you need a compact or sub-compact chainset paired with a wide-range cassette — think 34×32 or 34×34 — to keep a survivable cadence on the steepest ramp. Undergearing here means grinding at low rpm and burning matches you'll want on the givebacks. Check your chainset and cassette before the ride; the wall is not the place to discover you're one sprocket short.

Summary

• Length: 15.1 km
• Average gradient: 4.85%
• Maximum gradient: 23.27%
• Net elevation gain: 733 m
• Total ascent: 1271 m
• Category: 2

Sattel Pass rewards riders who read past the average. Gear low, pace to effort, and respect the 538 m of hidden climbing between the net gain and the total ascent.
