St Piran's Invitation, or Team SPI, is an adventure racing team named after Cornwall's Patron Saint.
The team compete in events covering a number of disciplines from adventure races to triathlons. However, the team's signature event is Winter Tough Guy.
The team has a broad range of members from all over the UK who all share one thing in common: a love for physical and mental challenges and an admiration of the beautiful scenery in the UK that we are lucky enough to train amongst.
