What is GO Mammoth?

GO Mammoth is the ultimate club for busy & active adults looking to maximise their spare time through playing sport, keeping fit & socialising with friends. 

As the UK's largest social sports & fitness club, GO Mammoth exists simply to make your life more fun... without the seriousness and commitment involved in joining a specialist sports club and x10 more social than joining a gym. Much like a uni sports & social society, we have something for everyone... 

So, why not grab some friends and enter any of the following as a TEAM or enter as an INDIVIDUAL and make a heap of new friends:

 After-work & weekend SPORTS LEAGUES (over 10 different team sports) all year round at the best indoor & outdoor venues

 Fun-focused FITNESS CLASSES from Cardio and Dance to Strength & Conditioning

 Legendary SOCIAL EVENTS throughout the year for anyone who loves a parteeeey!

GO Mammoth offers a diverse range of recreational sports leagues, fitness classes and social events for adults who want to play team sport, keep fit and make new friends without the competitiveness and commitment of joining a specialist sports club (where you might be expected to train multiple times a week). With the latest equipment, sponsor bars, regular socials and up-to-the minute online league standings, it’s the perfect way to unwind outside of work, have a buzzing social life, and keep fit.

It's a bit like a university or college sports & social club BUT for people with full-time jobs to hold down.. so you have the choice of loads of really fun sports plus the social side too. But because you work so hard you haven't got time to train, and plus these days you play sport for the social aspect and to stay fit rather than to make the olympics!

Our leagues are available to both the public and to corporates (see a few companies who play with GO Mammoth -  CLICK HERE)

I joined a league as an individual last Summer and met loads of people. It's great to play relaxed team sport again without all the seriousness of belonging to a proper club.
