1118.8 m · net rise 107.8 m · total ascent 110.5 m · overall 9.6% · evidence quality A (high) · Fließ · Tirol

Shape: sustained — 40% of the climbing sits in a quarter of the distance; longest continuous stretch at 10%+ is 171 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.

Dorf (Fließ, Tirol) is 1118.8 m long at 9.6% overall; its steepest 25 m averages 26.6% and its steepest 100 m 19.9%, measured from Austria's national 1 m airborne-laser terrain model along the mapped road centreline.

This climb's data: OCL JSON — the full gradient ladder, quality flags and provenance in the OpenClimb Ladder format.

Surface: GIP.at, Austria's official transport graph records no surface for this road; the map may tell you more.

Pending human review: the steepest stretch of this climb (196–221 m) looks like a track rather than a made road: the way under it is mapped as a rough farm or forest track (track grade 3 to 5) (about 100% of the steepest 25 m and 31% of the line). The figure is published as measured and has not been adjusted, but a climb whose steepest stretch looks like a track is listed, not ranked, until a person has looked.

Access: Listed 2026-09-13 (Austria wave 4 extent pass (public continuation kept)): road audit — way 1157929159: unnamed service way; way 1157929159: service way, surface untagged. Never silently ranked or dropped. Also trimmed 2026-09-15 at the tail dog-leg (a driveway); steepest 25 m now 26.6 %.

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).
