Overview

Inferno - Edales Ring of Hell was an August trail race in Edale, United Kingdom, organised by Tough Trails. Despite the severe name, the 45-kilometre route featured almost completely flat running with only 6 metres of total elevation gain, working out to 0.1 metres of climb per kilometre.

With an 11-hour limit, the required pace was 14.7 minutes per kilometre. Against 45 peer events in the marathon category, the cut-off was more generous than 77% of peers and tighter than 23%, giving runners an unusually wide cushion over non-mountainous ground.
