John Muir Way Nocturnal Ultra Marathon
The John Muir Way Nocturnal Ultra Marathon takes place on 7 November 2026. The format gives each participant six hours to complete as many laps as possible of a well marked, off road 5 km trail loop run in the dark. Entries are offered for solo runners and for relay teams of up to three people.
The loop passes a tented base on each lap where runners can access kit, food and supporter space. The event environment includes music, lights, food provision and communal areas, and the course runs under nocturnal conditions so participants are expected to bring trail kit and headtorch equipment. Distances covered depend on how many laps a runner or team completes within the six hour window.
Volunteer marshals support course checkpoints, registration, water stations and setup and teardown. Volunteers receive a race memento and a donation toward their club or charitable group.
In the event of extreme weather the race may be cancelled or rescheduled; entries will be transferred to a rescheduled date when possible and partial refunds are available in some circumstances. Withdrawal rules set transfer options and partial refunds with time based conditions and no refunds within 14 days of the event. Visit the organization's website for the most recent information.
