Immerse yourself in the serene beauty of Essex at Hanningfield Reservoir, where nature and competition intertwine for an unforgettable triathlon experience. Located between Billericay and Chelmsford, this picturesque setting offers stunning views across 870 acres of water surrounded by mature woodland, making it a haven for both wildlife enthusiasts and multisport athletes. The event features two main distances: the Sprint Triathlon with a swim of 750 meters, followed by a cycle of 25 kilometers and ending with a run of 5 kilometers. The Standard Triathlon challenges participants with double the distance in each discipline—1500 meters swimming, 38 kilometers cycling, and 10 kilometers running. In addition to full triathlons, there are Aquabike options for those who prefer not to run. Both sprint and standard distances offer a seamless transition from swim to cycle without the concluding run segment. The open water swim offers an opportunity to enjoy the reservoir's tranquil setting at your own pace before transitioning into either of the main events or participating solo in this scenic challenge. With no cut-off times, competitors can focus on their personal bests while enjoying the peaceful country roads and picturesque trails that wind around Hanningfield Waterside Park. The secure transition area ensures a smooth start to each leg of the race, complete with numbered racking spots for bikes and small bags or boxes allowed in designated areas. Live chip timing provided by Timing Up North keeps everyone informed about their progress throughout the event, culminating at the finish line where all participants are celebrated with bespoke metal medals. Refreshments await after crossing the line, along with a chance to purchase exclusive Wild Deer merchandise and an optional T-shirt for just £14.00. Free parking is available on-site, making it convenient for everyone to participate without worrying about transportation logistics. However, dogs are not permitted in any part of the reservoir as it is designated as a Site of Special Scientific Interest (SSSI). Don't miss this opportunity to experience one of Essex's most scenic and welcoming triathlon events!
