Running Tribe

Running Tribe stages looped races where participants enter a race rather than a fixed distance. Runners may complete one loop or continue for additional laps and decide how far to go on the day. Full course maps, elevation profiles and GPX downloads are provided.

Venues include Chalfont Park, Chalfont St Peter Community Centre, Amersham Shardeloes, Sarratt and Chesham. Only one course is used on any given race day.

Distances by course type:

  • Chalfont Park 10.8K loop: 10K, Half Marathon, 32K, Marathon, 34 Mile Ultra, 41 Mile Ultra
  • 7K courses: 7K, 14K, Half Marathon, 28K, 35K, Marathon, 50K Ultra
  • 5K courses: 5K, 10K, 15K, Half Marathon, Marathon, 34 Mile Ultra

Included for competitors are a finisher's medal for the distance completed, an aid station every lap supplying water, soft drinks and vegan and vegetarian food, drop bag access every lap, qualified medics on site, indoor bag drop and toilets, free parking, and manual timing with Webscorer with results published after the race.

Entry and conditions state participants must be aged 16 or over and comfortable covering at least one lap at the chosen venue. Walkers are allowed within the course time limit. Fields are capped at 70. Distance choice can be changed before the race or on race day. Transfers to another date are allowed up to the day before the race and refunds are permitted up to seven days before the event. Multi race pricing is offered for series entries.
