About the event

ShockAbsorberx240Shock Absorber are delighted to be title sponsor of the WomenOnly Triathlon! We’ll be supporting you all the way to the finish line and look forward to congratulating all age group winners with a free Shock Absorber bra!

This one is just for the females amongst us! Selected by 220 Triathlon as the UK’s number 1 triathlon for beginners, the Shock Absorber WomenOnly Triathlon has evolved into a full female-only multi-sport day. Take your pick; there’s something for everyone. So, whether it’s about taking on a challenge for the first time for the official charity Breast Cancer Care, or just to challenge yourself to better your time, the atmosphere at Dorney Lake makes this the perfect event at which to do this.

The event, held at the Olympic rowing venue Dorney Lake, Eton, provides a flat tarmac run and bike track as well as a lake with clean, calm waters to swim. As well as being a very safe and supportive venue, it also offers superb spectator viewing.The triathlon is always popular, offering a range of distances to either dip your toe into the water for the first time; to push yourself with a longer distance; or even to challenge yourself against the best in the Sprint Distance Triathlon.

So what are you waiting for? Get your friends together, join up, have fun and maybe even raise money for Breast Cancer Care. If this is your first foray into open-water swimming or triathlon, why not take advantage of some extra training and advice at one of our triathlon training days or open water swim seminars at Dorney Lake in May? Title sponsor, Shock Absorber are the UK’s leading sports bra brand, celebrating 15 years of providing expert sports bra support and will be on hand to offer advice. There are no muscles in the breasts, only skin and Cooper’s ligaments support breast tissue. Any excessive amount of breast movement puts strain on these ligaments causing them to stretch. Nothing can naturally restore them. Wearing a Shock Absorber sports bra will help to prevent long term damage to your breasts during exercise.

Spice Girl, Melanie C: “The Shock Absorber Women Only challenge is a fantastic celebration of women in sport. It allows ladies to compete in an environment which is encouraging and fun. Women contribute so much to the world of sport and these events offer a chance for all women to get involved regardless of their age or ability.”

We are often asked if wetsuits have to be worn at our events. But the wearing of wetsuits in triathlon is governed by British Triathlon rules and is totally dependent on water temperature one hour before the start of the event. Read the wetsuit rule for triathlons HERE.

Please see the Public Health England – Swim Healthy PDF



These results are provisional, and any queries should be sent to our Results Crew. These are compiled and any changes are shown in the final results here around a week after the event. If you are looking for results from previous years, please visit the main Human Race Results page.

We are often asked if wetsuits have to be worn at our events. But the wearing of wetsuits in triathlon is governed by British Triathlon rules and is totally dependent on water temperature one hour before the start of the event.

Water Temperature Wetsuit Rule
Water Temp less than 14 degrees Wetsuits are COMPULSORY
Water temp 14 – 22 degrees Wetsuits are OPTIONAL
Water temp above 22 degrees Wetsuits are BANNED

We do say that wetsuits in fact help with buoyancy and warmth, so we strongly recommend that you wear one if they are optional. We will keep you updated with water temperature as we get closer to the event but at Dorney Lake it is almost always an optional wetsuit swim.

“Breast Cancer Care was there for me from day one. They’ve given me so much support through their helpline, network and Younger Women Together weekends. Through their support, I’ve learnt so much and have made friends for life.

Unfortunately, my cancer has spread and after over three years of treatment I still have breast cancer and need regular chemotherapy.

Breast Cancer Care is still here for me and is a charity that I rely on in so many ways. Thank you for taking part and helping someone like me – you’re making a huge difference to the free support services that Breast Cancer Care offers.”
