Over the last few years female participation has been increased to 38% by adding a greater variety of distances, female-only waves, launching the virtual series and making strategic partnerships.

Completed the mixed team relay for a bit of fun with a 1 member who never completed a triathlon (I think she's hooked now) and another girl who has done just a few and it was a great team event that we pushed each other on. this is a great event to do to be competitive or just for a bit of fun. well organised and great course. Gabriel W

Brilliant. Emmanuel H

Very well organised. All crews and Marshalls were very helpful and encouraging. Lovely course. Joe L

First triathlon here, but had a few aquathlons before here. Great organization as usual, marshalls guide us well and things just go smoothly. Everything well marked. I enjoyed it a lot! Thank you for keeping high standards! You guys rock. Tomasz C

Outstanding. Nick H

It was my first triathlon and I throughly enjoyed it. It was well organised and a smooth process throughout. I really liked that there numerous areas for my supporters to see me. I definitely would do an event again. Aoife S

I had entered the marathon but didn't feel up to it so switched to the 10k. Staff were so lovely and made it such an easy transition. Everything was run so well from the parking, bib pick up, race briefing, course marking and finish were all fantastic. Could not fault anything at all. Highly recommend! Sandy C

I arrived from Germany with a bad knee and was very worried that I wouldn't be able to run. And then I met this great team ♥️ I would like to thank everyone for your warmth, friendliness, encouragement and support before, during and after the run. You are incredible. If I ever get to run a half marathon again, I will come back and do it with you. Thank you for everything. Your Tanja. Tanja G

1st time at this event and 1st 5k swim best ever. Couldn't fault anything about the whole event for me. Thanks for such a great experience. Judith xx Judith M
