Proving Grounds UK is the functional fitness competition with the athlete and spectator at its heart!

Our goal over the last 5 years hosting Proving Grounds is, and always will be, to make the “athletes feel like superstars” and give the crowd and athlete an experience they will never forget.

Proving Grounds UK provides one of the UKs top fitness competitions for all levels of athletes from our “everyday” fitness enthusiasts, Intermediate grafters to our RX/Elite competitors.

The spectator experience is all about being close to the action as well as bringing top name vendors and spectator exhibits to the event.
