Event history

Running Tribe events were borne out of the frustrations of founder Steve who, after completing 77 miles over 23 hours ended up walking away with nothing to show for his efforts after succumbing to an old injury. Running Tribe events are a bit different.

Race training can be relentless but necessary to perform your very best on the day. You know you run better relaxed but sleep, nutrition and even that niggling injury all have to be in check too! In truth, there’s a lot that can get in the way of you finishing your full race distance. And when that happens, it’s gutting. Worse still, the distance you do manage to cover doesn’t count for anything. No medal, no congrats. Just the shame of handing over your number and slipping back to the car park empty-handed. Running Tribe thinks that’s wrong and are changing it, one race at a time.

Race & Train

Running Tribe courses are circular routes of a minimum of 10.6k and you can attempt as many loops as you feel able to on the day. You’ll have one of the best-stocked aid stations on the events circuit, packed with everything from baked goodies to energy gels and, as your kit bag will always within reasonable reach you can use your pitstop to test out different fuelling techniques and running gear along the way.

I had an excellent experience with the running tribe February race! The format of multiple laps with a well-stocked food stop at base camp every 10km was just perfect for training run or for someone to complete their PB distance! I would highly recommend entering and running your distance! Gavin D
