Shape: sustained — 29% of the climbing sits in a quarter of the distance; longest continuous stretch at 10%+ is 255 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 the GIP.at road network, 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: unpaved (100% unpaved), according to GIP.at, Austria's official transport graph: surface unrecorded for the first 20 m; unpaved for the first 67 m; surface unrecorded from 67 m to 197 m; unpaved from 197 m to 715 m; surface unrecorded from 715 m to 892 m; unpaved from 892 m to 1,611 m; surface unrecorded from 1,611 m to 2,309 m; unpaved from 2,309 m to the top. The steepest 25 m lies on the unpaved part.

Access: Road authority marks this road under a general traffic restriction: motor traffic limited to agricultural, forestry or permit holders; bicycles are normally allowed — check local signs.

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).
