Ely Tri Club Runfest 2026

Ely Tri Club Runfest is a running festival held in October at Palace Green in Ely. The Half Marathon begins and ends outside Ely Cathedral. The event features out-and-back courses with multiple distances: 10k, Half Marathon, Marathon, and an ultra option. This caters to runners seeking anything from a shorter mixed-surface run to a longer endurance challenge. The Half Marathon covers 21.1 km on tarmac and compact trail along Cycle Path 11, with a turnaround point in Wicken village. Courses are marked, results are timed, and the event has a 300-participant limit, closing registration when full. The Runfest originated as an ultra event, with the Half Marathon introduced as the festival expanded beyond its initial long-distance focus.
