A triathlon series offers triathlon events for beginners right through to pro-triathletes. These are great for anyone who likes to have consistent and regular tri challenges to compete in throughout the year. We work with the UK’s largest triathlon series organiser - The Castle Triathlon series.
These guys organise renowned super-sprint, sprint, standard (olympic) and long course (ironman) triathlons in iconic castle locations across the country.
