I have limited experience myself but can highly recommend Amie Phillips at the Stow Leisure Centre for sports Therapy/Massage and I saw a Physio called Matt at Stow Health in Violet Hill Road last year who seemed to know his stuff.
After chatting to our own Bob Grainger at Striders in the last few weeks though I suggest checking out his new service offered from Bodywise in Stow - he is highly regarded by many at the club.
