Overview

Organised by Albion Running, the Ham & Lyme 100 Km Run followed an out-and-back route along the Liberty Trail between Lyme Regis and Ham Hill Country Park. Across the 100 km course, runners tackled 5660 metres of elevation gain, working out to 56.6 metres of climb per kilometre.

That gradient made the 15-hour time limit demanding. Requiring a minimum pace of 9 minutes per kilometre, the cut-off was tighter than 69% of 100k races and more generous than 31%, leaving little room to recover lost time on the steep terrain.

With 24 finishers in 2022, the race drew a compact lineup—smaller than 61% of 100k fields and bigger than 37%—costing an entry fee of £60 across its 5 editions held between 2016 and 2022.
