In August 2000 Royce Gracie The Ultimate Fighting Champion, made the first of many trips to the UK. Simon attended his seminar and it very quickly became clear that along with many other martial artists, Simon's ground fighting skills needed honing to become fully rounded as a martial artist. Soon after this Simon was invited to tour Japan with Royce for two weeks, travelling with Royce on his seminar circuit. Simon  was also invited to Japan to watch Royce fight at Pride.

Simon currently trains with Roger Gracie and the Black Belts at his academy 2-3 times a week.
