Good stuff!

The nearest gyms to Hadleigh are:

Evolution Gym - Leigh
TSG Fighting Academy - Westcliff
Dojo - Canvey
5 Elements - Basildon

Evolution and TSG are out-and-out MMA clubs. I don't know too much about Dojo but James will know more soon. 5 Elements do some grappling but MMA isn't their main thing.

Scott Gammer is a pretty big name in UK boxing! I think he's had a pretty tough couple of years recently but he was a top talent (for UK standards anyway!). I think Audley Harrison or Danny Williams knocked his '0' record eventually.

Your mate must be pretty tasty at Judo if he's fighting at national level! Is he thinking about doing a bit of MMA as well?
