Great organisation

Great organisation, lovely helpful staff members. I called up several times during the process of submitting a team to a local netball league and they were always helpful and forthcoming with information.

Super useful system

Love being able to book easily through the platform, and gather ringers whenever we need. Go mammoth are always quick to respond and last week they arranged for an amazing ref! Great system, thanks GM!

Go Mammoth Review

Go Mammoth gives the opportunity for everyone to sign up and play a range of sports. Really enjoy the netball league and they have been helping in accommodating different requests. Currently playing in a great league of netball and would recommend to others.

Fun, sport and exercise all well organised

Really nice group of people for fun, exercise and sport. Well organised and makes a regular week fun by getting exercise and having some laughs with sport. Second time have played in the five a side mixed league which has been a really positive experience.

Standards in steep decline

Year after year Go mammoth basketball deteriorates. Not enough referees and table personnel, poor locations, poor communications with management as the standard of plays keeps getting worse. As a result, good teams leave, and so will mine. It feels like GM keeps spreading itself too thin, prioritizing adding more venues and scheduling more sessions, rather than optimizing the existing ones. I've played for three straight years now and it's never been perfect, which is fine. It's a rec league. But in the last two weeks, for example, mistakes and confusions with the table and the referee have tainted the end of games. This has resulted in really poor experiences.

When we complain, the customer service is at best dismissive, if at all responsive.

Our team will leave, as will three others which will mean this slot will shut down. It used to have eight competitive teams and it will simply not go on.

If nothing changes this will be the fate of every slots at this location.

Will not replace faulty equipment

Go MAMMOTH refuse to replace the faulty basketball rims at our Hackney Downs league and hide behind school bureaucracy - it is their job to provide valid equipment for us to use. We all pay a lot of money and they clearly do not care.

Save your money and play elsewhere

Hi there,

Thanks for your feedback. We’re really sorry for the experience you’ve had at our basketball league. The condition of the rims has not met the standard we expect for our leagues.
To clarify, we do not own our venues and have been requesting repairs from the school every week for several months with no positive response. We’ve also sourced independent quotes to try to speed the process up and to fix the problems at our own cost but we completely understand how this impacts your matches.
As this situation is not acceptable to us either, we are moving the league to a new and improved venue next season to ensure reliable equipment and a better playing environment.
We genuinely apologise for the disruption and appreciate your patience while we’ve worked to resolve an issue.
Please reach out if you'd like to discuss further.

Kind regards,

Team GM

Inconsistent service

I have been playing wifh GoMammoth for about 2 years. Their service is quite inconsistent. Some of the referees are good, some are not so good. The prices feel very high for short game times, which seem to be getting shorter. We used to be allowed to play until 930pm in my evening league and now they kick us out at 9pm. It's discouraging to hear that we're now paying the same price for half an hour less of time.

Go Mammoth are fantastic

Go Mammoth are fantastic. It’s great to be able to just turn up without worrying about bringing any equipment. The umpires are always friendly and fair, and the games are consistently good fun.

Value for money could be better

Great to have a space play and the level is good, but a bit too expensive for what it is. Would love to get a better value for money (more sessions in the league, more teams, etc)

A great way to socialise

Gomammoth is a great social sports organiser.
If new to London, it is a great way to make friends with a common passion/interest in a sport. Made great friends since I came to London 9 years ago.

I have played volleyball, Softball and dodgeball with them.

My experience has been great

My experience has been great. I’ve now played for two different leagues and really enjoyed it. The umpires are friendly and professional. The teams all get along and it’s easy to make friends there. Would highly recommend to everyone to get involved!
