She joined TLA late in 2010 and is a regular instructor at the outdoor classes, as well as running the School Run Bootcamp classes in Wootton and Sunningwell. She teaches kettlebells and strength classes as well as Personal Training for a number of clients.

She is also a very keen martial artist and has won medals in Brazilian Jiu Jitsu and has been known to take part in the odd obstacle adventure race. She has competed Internationally in Triathlon, representing Great Britain at both European and World Championships.
