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.

Finishers medal

Whether you manage to finish an ultra marathon, marathon, half or 10K, the distance you run will be celebrated, no matter what you set out to complete originally. That way, no matter what kept you up the night before, there’s still a reason to turn up and give it your everything.

Entry fees

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

Another fantastic event from Running Tribe. Organised by runners for runners. Very well stocked aid stations and clearly marked route. Will definitely be back for more RT events! Alison H

First time at a Running Tribe event and really enjoy it. Will definitely participate again soon. Thanks. Craig R

Always a pleasure to run with Running Tribe. Lovely courses, with a variety of distances to choose from (and can even change distance on the day). Great medals, excellent newly designed T-shirt (included in the entry fee!), plenty of refreshments, and friendly family staff! Thank you! Adam W

Wow, my first ultra and couldn't have wished for a better race. The loop format really suited me as I could leave a change of kit and nutrition at the base. Beautiful course, starts on paths and then into woodlands and trails before emerging back onto paths back to base. Quite kind on the legs. Organisers were friendly and helpful and will be returning. Thank you for helping me achieve my goal!!!! Christopher B

I ran my first Running Tribe event on 25th November and absolutely loved it! I usually run in a great big rhino costume and the Rhino and I could not have been made more welcome!! What a kind, encouraging, generous and supportive team or rather “Tribe” they are!! Thank you Running Tribe! I’m already looking forward to seeing and running with you again very soon! ❤️🦏 Chris G

Very easy going friendly vibe from all those that organized it. Low key event but that’s what made it nice. 5 stars and hope to do one again soon! Nick C

Really great fun! Intimate and friendly event with great organisation, and a lovely course :) Matthew S

My friend and I turned up in Gerrards Cross planning to run a marathon and ended up running an ultra! We wouldn't have attempted it if it hadn't been for the great support and encouragement of the Running Tribe team - husband and wife, and medic Colin. Colin strapped our poorly toes up, was great to chat to and Steve and his wife provided us with delicious snacks (vegan friendly) and lots of encouragement. The whole team were so friendly, laid-back and supportive. Really loved the event and would recommend this team to anyone wanting to run a 10k, half marathon, marathon or ultra on a well-supported, scenic and mainly trail route. Thanks to all the great marshals too! Catherine M

I really enjoy these events and will be back for more. Great courses and a really friendly team. Susanna G
