Discovered lane (52.2837, -2.3727)

902.5 m · net rise 70.3 m · total ascent 74.9 m · overall 7.8% · confidence: high · Great Witley · Worcestershire · share

Shape: sustained — 35% of the climbing sits in a quarter of the distance; longest continuous stretch at 10%+ is 73 m.

Not yet matched against documented climbs — the measurement stands on its own.

Gradient ladder what do windows mean?

Window	Maximum	Located at
2 m (diagnostic)	≈47%	894–896 m	under overhead cover terrain reads 63.9% at 149–151 m across a structure — excluded
3 m (diagnostic)	≈45%	893–896 m	under overhead cover terrain reads 50.8% at 149–152 m across a structure — excluded
5 m	38%	422–427 m
10 m	31%	421–431 m
20 m	21.6%	876–896 m
25 m	20.9%	872–897 m
50 m	20.0%	847–897 m
100 m	15.2%	797–897 m

≈ appears only on the 2–3 m diagnostic rows here, which does not lower the confidence letter: those windows are never headline values or ranking keys, so confidence reflects the standard (5–100 m) windows — which are clean on this climb.

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

Access: Held from rankings 2026-09-04 (D21 C, hidden-steeper re-line): re-lined onto the bench the EA point cloud finds, but under the traced line's 25 m maximum the cloud reads flank, ambiguous or absent — not a plain road bed — so neither the published nor the re-lined number is verified. Published number stands; off the rankings until a cross-section look.

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 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.
