Bowels of Fleetwith Fell Race

The Bowels of Fleetwith is an organised fell race based at Honister Slate Mine in Borrowdale, CA12 5XN. Entries opened on 20 November 2025 and close on 3 July 2026. The event has an entry fee of £30.00 and is open to competitors aged 16 and over; under 18s must be accompanied by a responsible adult.

Competitors start from Honister Slate Mine and wear a helmet and headtorch for an initial half mile uphill section before entering purpose‑designed underground mine tunnels. The underground route includes about 1 km of narrow passageways, inclines, and chambers that are not normally open to the public. After the mine section the course climbs to the summit of Fleetwith Pike (648 m), traverses to Grey Knotts (697 m), and then descends back to Honister Slate Mine. The total distance is a little over 6 km with approximately 1500 m of ascent. The underground passage was prepared by Honister Slate Mine staff to provide a controlled route through previously restricted areas. Visit the organization's website for the most recent information.
