Hillingdon Cycle Circuit Kids Duathlon | Tristar 3

We've been organising children's duathlons and triathlons for the past 10 years at various venues including Dinton Pastures, Tywford and Eton Dorney Lake. We're super excited to bring this new venue to our event calendar and have witnessed first hand just how much fun can be had at this venue. We're also very excited that this event is part of the Triathlon England South Central Junior Series. This venue is great for competitors and spectators alike with a tarmac cycle and run course and banked grass verges for spectators. All races are run–bike–run duathlons with distances set by age category. Races use a traffic-free circuit and are timed using chip timing. Ages are based on age as of 31 December 2026, not the event date. Distances are aligned with British Triathlon Rules for Duathlon (page 38). Exact distances will vary slightly. Suitable for all abilities of duathlete - even if it is their first one, everyone has to have a first event somewhere and we would love it if you choose for it to be with Barnes Fitness.
