Our 2019 Race Calendar will be available soon.

Registrations open for ‘The Islander’ 12th November.

Thank you Abbie & Josh for a fantastic season of racing!!! Great location, great people, great races. I would definitely recommend these events to anyone. Looking forward to 2018


Possibly best race medal ever - it's only a bloomin' bottle opener as well!!! Thank you Mersea Island Races for a great sprint Duathlon this morning.

As a junior it was fantastic to compete in adult race and have so many others my age. Such a friendly atmosphere with great support. Look forward to your next event.


Fab event! We loved it - Thank You!


Thanks for organising and hosting us on your beautiful island.


Thank you so much for another great race yesterday. So lovely to race in a family run event that is friendly...will defo be looking out for the 2018 dates.

Brilliant event, very well run. Many thanks 👍


Thanks all for putting on a great event - really enjoyed it. Well done Charlie and Jen!


Really enjoyed it. Looking forward to trying it again next year already!


I thought this event was fantastic. Very well run and amazingly friendly, marshals were superb and deserve a lot of thanks, I do not think I have ever been to an event where everyone supported each other right until the end. Although, I was dreading the beach run the support from people on the beach was terrific. Looking forward to next year.


Today was brilliant ! I was nervous as this was my first ever triathlon and even more so when i turned up the only one on a mtb ! Everyone was really nice and helpful and supportive 🙂 the event was super organised and my fear of getting lost on the cucle and run was put aside with all the very helpful signs and really encouraging marshals ! Can't wait to do another thank you for making us feel so welcome 🙂



How it all began...

Mersea Island has hosted a Sprint Triathlon for 6 years running. It started due to Josh realising Mersea was not only an idyllic setting but perfectly formed to provide a unique arena to stage such an event.

The Island

Your adventure starts when you arrive at Mersea Island. You approach Mersea by a causeway from the mainland – yes, the island gets cut off at high tide! At just eight miles square….
