Shape: sustained — 33% of the climbing sits in a quarter of the distance; longest continuous stretch at 10%+ is 225 m.
Found purely from mapping and LiDAR data, and not yet matched against books, race records or lists — it may be well known to locals under a name we've never heard. It was cross-checked against swisstopo’s swissTLM3D road model, OpenStreetMap and a second terrain model, but a discovery can still be an artifact of the terrain model or the map. Treat it as a well-evidenced hypothesis until someone has ridden it. If you know this road, tell us what you found — photographs, corrections and local knowledge all welcome; the map links below let you scout it first.

This climb's data: OCL JSON — the full gradient ladder, quality flags and provenance in the OpenClimb Ladder format.
Surface: mixed (35% unpaved), according to swisstopo's swissTLM3D road model: paved for the first 391 m; unpaved from 391 m to the top. The steepest 25 m lies on the paved part.
Access: Listed 2026-09-10 (Switzerland run 6): road audit — way 232485602: service way, surface untagged; barrier gate (no) 90.6 m off route. Never silently ranked or dropped (Peter, 2026-08-27).
Measured, not vetted. This page records what the laser record shows about the road's shape — nothing more. Nobody has necessarily ridden or inspected this road for the survey, and a page here is not a recommendation and no guarantee that the road is open, surfaced, rideable or safe. Gates, private sections, missing rights of way and hazards do not show up in elevation data. Check access and conditions on the ground and make your own judgment.

Profile
The map, profile and gradient chart share one position — move your pointer over them and the marker follows. Colors are the gradient bands; the shaded span is the steepest 25 m. Any 25 m figure is good to about a point either way (why).
