Warland Gate
1021.3 m · net rise 110.1 m · total ascent 117.1 m · overall 10.8% · confidence: good · Warland
Shape: sustained — 35% of the climbing sits in a quarter of the distance; longest continuous stretch at 10%+ is 207 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.
