Levencorroch Hill to Levencorroch°

817.1 m · net rise 55.3 m · total ascent 56.7 m · overall 6.8% · confidence: good · Levencorroch · North Ayrshire

Shape: stepped — 59% of the climbing sits in a quarter of the distance; longest continuous stretch at 10%+ is 158 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 (55.4467, -5.1554)'). Corrections welcome.
