The 25th Anniversary Hatch End - Harrow Triathlon

Jetstream Tri Club are pleased to announce that this popular family-friendly event returns on Sunday, 11 May 2025 - 25 years since it began!

If you're looking to build race experience and confidence, this is the ideal one for you! The pool-based swim and friendly atmosphere, make the Hatch End - Harrow Triathlon the perfect starter race for both adults and juniors new to the sport. The event is also a favoured warm-up race among experienced triathletes.

The adult race includes a 400m pool-based swim (at Hatch End swimming pool), followed by a 17km road cycle and finishes with an off-road 3km run. There is an expectation that you will be able to complete the swim in under 16 minutes and the cycle in under an hour.   

This year, in celebration of the event's 25th anniversary, an ADULT RELAY option is available. Relay teams can be mixed format and consist of 2 or 3 people.

Juniors cycle on the playing fields rather than the roads with age-appropriate adjustments to distances (see table below). See hatchendtri.com for more information.

Note: Triathlon age is measured at 31 December of the race year, not the day of the race. Unless your birthday is early in the year your triathlon age will often be 1 year older than your actual age on race day.

Race Distances & Early Entry Fees

*Additional British Triathlon day licence/insurance fee for non-BTF members: £8 for adults, £2 for juniors.

**Each individual in the relay team will require their own race pass (teams can consist of 2 or 3 people).
