Take on a unique multisport challenge at the Thorpe Park Sprint Triathlon, where you'll swim, bike and run around one of the UK's most exciting theme parks. With Sprint distances, this event is perfect for first-time triathletes looking to experience the sport, as well as experienced athletes chasing a fast and enjoyable race.
Your race begins with a 750m open-water swim in Fleet Lake, completing one buoy-marked lap with clear sighting points before heading out onto a flat 20K bike course. Finish with a 5K run on smooth, fast terrain, creating an ideal course for confident pacing and personal best attempts.
Every stage of the event is clearly marked and fully supported by experienced marshals, ensuring a safe and enjoyable race-day experience from start to finish. Whether you're completing your first triathlon or looking to improve your time, you'll enjoy fantastic organisation and a welcoming atmosphere throughout.
As an added bonus, every entry includes FREE admission to Thorpe Park Resort, giving you the perfect opportunity to celebrate your achievement with a day on the rides after crossing the finish line.
