Welcome to TriFerris Promotions, organisers of the Swindon Duathlon, Cotswold Sprint Triathlon and Tomac Off-Road Duathlons.

Over the years our events have served as BTA National Championships, Age Group Qualifiers for the ITU World Championships but have never lost their underlying reason for existence: for you, the athlete, to have a good, enjoyable race.
