Fortitude: Denbies

The date for Fortitude: Denbies is confirmed as the 27th of September 2025 and entries are now open!

The rules of the challenge are relatively simple.

You will be awarded an event medal and coloured finishers shirt based on your ability to complete 10 laps of our roughly 3mile, 4mile or 5mile loops in the given time.

You can change down distance at any time based on how the day is going but you must complete all 10 laps and return to the race village within each hour. Failure to complete a lap and return to the start within the hour will mean you can’t progress onto the next hour.

Your finishing grade is determined by your shortest loop – not total mileage.
