The World’s Longest Single-Day Triathlon Launches – 255 Triathlon

A brand new formatted event called the 255 Triathlon has been launched by TriBourne Multisport Events, organisers of the award-winning Eastbourne Triathlon. The gruelling physical event will become the longest single day triathlon in the world and will take place at Goodwood Motor Racing Circuit, West Sussex, located near Portsmouth.

The first edition of the race is limited to 300 competitors who will take on the 5km swim in the nearby Westhampnett Lake before making their way onto the historic motor racing circuit for a hefty 200km 52 traffic-free laps. The athletes will then hop off their bikes and take on the final leg consisting of a 50km 10 lap run on the circuit’s perimeter path. Competitors tackling this ultra-endurance event will have up to 18 hours to complete the distance.

Being a traffic free multi-lap format this race offers a great athlete-spectator experience. The pit lane will provide the focal point of the event with spectators able to support athletes continuously throughout the day. With music, commentary, live lap timing and leaderboards, this will provide a race experience like no other. 

Race Director, Matthew Dowle, said ‘Ironman has always been widely regarded as the ultimate single-day endurance event. We feel the time is right to introduce the next step for endurance triathletes. 255 Triathlon will not only push competitors to a new level of physical and mental endurance but will also provide an unparalleled level of engagement for spectators throughout the whole event. We’re very excited to share our vision with the triathlon world.’
