Bowels of Fleetwith Fell Race
The Bowels of Fleetwith Fell Race is a set of two trail events held at Honister Slate Mine in Borrowdale on 27 June 2026. The event offers two distances:
- 5 km
- 10 km
Both routes combine open fell running with a compulsory underground section through old mine tunnels. The subterranean course is about 700 m long and includes steep inclines, mining ladders and large chambers. Runners pass through the mine and emerge roughly 100 metres above the point of entry before continuing on the fell to the summit of Grey Knotts (697 m) and then descending via the tramway to the finish at Honister Slate Mines.
Routes will be fully flagged and marshaled so there is no navigation or map and compass requirement during the race. Safety equipment is specified for the underground section; helmets and headtorches are required for entry into the mines. Minimum kit requirements include a waterproof top and bottom, hat and gloves to be carried on the course. Organisers will spot check finishers for required kit and may disqualify runners who remove required kit before the race.
The event is open to participants aged 16 and over; under 18s must be accompanied by a responsible adult. Entry fees listed are £30 for the 5 km and £35 for the 10 km. Prizes are awarded in overall and veteran categories. Visit the organization's website for the most recent information.
