Ranking metrics are derived from the published methodology and appear only when the required inputs exist.
The data coverage page shows which route, cost, finisher and scoring signals are currently available across the race estate.
Route-led rankings link back to stored route geometry and elevation profiles where the source data supports them.
Use flat-grade share, GAP factor and ascent context as a route-first shortlist before checking conditions, field and logistics.
Compare ascent, climbing per km, steepest grade, descent and low-ascent alternatives.
Conditions rankings use typical temperature, wind and rain signals where the race page has enough held data.
Ranking pages are generated from the same source-backed race data used by the public race pages. Route-led rankings use stored route geometry and elevation profiles where available; score-led rankings appear only when the required inputs exist.
A ranking page is published only when enough races have the required source-backed metric to clear the thin-page guardrail. The current index exposes 138 qualifying ranking pages.
No. The rankings prioritise races with enough evidence for the chosen metric. Race pages can still exist without appearing in a specific ranking when their route, cost, score or calendar evidence is incomplete.
Each ranking links through to race pages with source provenance, as-of dates and available route evidence. The data coverage and methodology pages explain which signals are populated and how unsupported metrics are withheld.
