Experience the thrill of triathlon competition at an iconic Olympic venue where athletes from around the world have achieved greatness. This draft-illegal race offers both Sprint and Standard distances for those looking to test their mettle on flat, scenic terrain that lends itself perfectly to a chip-timed personal best. The crystal-clear lake provides a serene environment for swimmers, while the bike course winds through picturesque grounds offering stunning views at every turn. The run follows suit with its level path, ensuring a smooth and efficient transition from cycling to running. For those who prefer not to tackle the full distance or are new to triathlon, an Aquabike option is available, combining swimming and biking without the run component. Additionally, relay teams of two or three can share the disciplines for a collaborative race experience. Race day starts early with the Sprint Triathlon beginning at 7:30am, followed by the Standard distance event at 8:30am. A Super Sprint Triathlon kicks off at 10:00am, offering an even shorter and faster-paced option for those seeking a quick challenge or introduction to triathlon racing. To participate in this event, all competitors must be members of British Triathlon with either an annual Core or Ultimate membership or a single-use Race Pass purchased alongside their entry. For added comfort during the swim portion, Zone3 wetsuits are available for hire on a seasonal basis as well as daily, weekend, and monthly rentals. With ample support from race staff throughout the course, this event promises an encouraging atmosphere that will push you to your limits while celebrating every milestone along the way.
