Shape: sustained — 38% of the climbing sits in a quarter of the distance; longest continuous stretch at 10%+ is 103 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 OS road network, surface models and map tags, 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.
° The name is provisional: this climb is not yet matched to a documented name, so it was named from nearby map places. There is no evidence of local usage — (auto-named from gazetteer (hypothesis, unreviewed); discovered as 'Discovered lane (57.9096, -5.1800)'). Corrections welcome.
needs review short_window_divergence — treat short-window maxima here as provisional.
Gradient ladder what do windows mean?
| Window | Maximum | Located at | |
|---|---|---|---|
| 2 m (diagnostic) | ≈46% | 67–69 m | under overhead cover terrain reads 62.2% at 183–185 m across a structure — excluded |
| 3 m (diagnostic) | ≈45% | 66–69 m | under overhead cover terrain reads 55.9% at 183–186 m across a structure — excluded |
| 5 m | ≈45% | 64–69 m | under overhead cover terrain reads 47.8% at 182–187 m across a structure — excluded |
| 10 m | 35% | 61–71 m | |
| 20 m | 27.8% | 57–77 m | |
| 25 m | 24.7% | 57–82 m | |
| 50 m | ≈14.8% | 51–101 m | under overhead cover terrain reads 15.1% at 171–221 m across a structure — excluded |
| 100 m | ≈13.5% | 200–300 m | under overhead cover terrain reads 14.5% at 181–281 m across a structure — excluded |
