How we ranked these

Races are ranked by Modelled true cost. Score metrics use methodology scoring-methodology-v1.0. Route, elevation and fee metrics use the sourced or derived value shown in the table. A ranking is only published when at least five races qualify, so the table is never padded with thin data.
