How steep is that hill, really?

It depends how far you measure — the same hill can honestly be 32% over 2 m and 25% over 100 m at once. So every gradient published here states the distance it was measured over, computed from national laser surveys by one published method anyone can re-check. One survey, country by country, wherever open LiDAR exists.

Measured from open dataEvery value is computed from professionally flown national LiDAR — never copied from a sign, a book, a GPS trace or another database.

Every maximum states its distanceA bare percentage can’t be checked. A percentage with its measuring distance can — that discipline is the survey’s published data format.

Shows its workingConfidence, quality flags, provenance to the exact survey tiles, and a machine-readable document on every climb — plus a methodology that documents how the numbers are policed.

The steepest 25 m — one cross-survey ranking — paved roads

Current coverage: the UK and the New England surveys — not the world. Every published climb the crown rules admit (measurement confidence High or Good — the A/B letters in the data), ranked together by steepest continuous 25 m — all 1685 of them; shown here are the cross-survey top 100 plus each survey’s top 25 at their true ranks. Ranked by one steepest window, a row may be a brief sharp pitch on an otherwise gentle road or a sustained traditional climb — the Length and Overall columns tell you which. ≈ marks values under tree cover or structures (less certain — the flag does not say whether the true value is higher or lower). US surface chips come from each state’s road inventory; UK climbs are paved public roads by survey scope. Surface: · Caveated rows: (ranks stay the true ranks) · Country:
