jon is a black belt  – which were started after ‘a bit of a push’ from his eldest daughter, demanding she be able to train more (she was just 5 at the time!). He also coaches on the Ultra MMA courses, preparing everyone for their charity fights.

He previously trained in Muay Thai, Boxing and MMA over the years, which showed him the joys of grappling and lead to him focussing on Brazilian Jiu-Jitsu in 2013, where he currently holds a Brown belt.

Keen to challenge himself, Jon has run many of the obstacle courses and mud races including Tough Mudder, Spartan Beast, Grim Challenge and the Rat Race where he tackled 200 obstacles over the 20+ mile course! In BJJ he’s competed and medalled both regionally and nationally through the belts and is looking forward to returning to the competition mats to break in his Brown belt.
