For the first time since 2014, we are bringing back the Harwich Olympic distance triathlon. 

Race HQ and transition will be on the grass along Lower Marine Parade, next to the oval shelter, in front of the Lighthouse Sports and Social Hub. 

Starting with a 1500m sea swim along the Blue Flag beach of Dovercourt Bay, swimming out from Earlhams and along the bay, before going around the iconic lighthouse and heading back to shore. Followed by a 40km bike around the villages surrounding Harwich. Finishing with a fast and flat 10km (made up of two laps) along Harwich promenade. 

We are also offering a 2 or 3-person relay option, so you can take part with friends or family, each person doing a different leg and coming together to cross the finish line.

The first wave will be set off at 10:00, with different waves for men and women. 

Please note - If a sea swim is too risky on the day due to bad weather, we will revert to a duathlon. No refunds will be possible.

Total Spaces: 120 Individual + 30 Relay Teams 

Entry Cost (Individual): £50 (includes BTF day licence)
Entry Cost (Relay): £60 Per Team (includes BTF day licences)

The Junior races are all based out of Dovercourt Bay Lifestyles swimming pool and will involve a pool swim, a cycle on grass and a run on grass.

The event is open to children aged 8-15. Ages are based on the child's age as of December 2025 (therefore all children born in the year 2017 are considered 8 years old for the event and can take part). To make it as accessible as possible, we offer three distances for age groups: Under 9s, 9-12s and 13+.

• Children Under 9: 50m pool swim, 1km cycle on grass, and 600m run on grass.

• Children Aged 9-12: 150m pool swim, 2km cycle on grass and a 1.2km run on grass.

• Children Aged 13-15: 150m pool swim, 3km cycle on grass and a 2.4km run on grass.

Juniors taking part must have their own road-worthy bike (no stabilisers) and helmet. All sections of the event must be unassisted, and therefore all juniors taking part must be confident they can independently complete all three disciplines of the triathlon (but we have plenty of super friendly and helpful marshals who will be on hand throughout all of the transitions and sections of the race). 

Medals will be awarded to all finishers! 

Total Spaces: 100

Entry Cost: £5 (includes BTF day licence)
