Innovative long distance triathlon format at Goodwood


The 255 Triathlon consists of a 5km swim, 200km bike and 50km run with participants able to take part as individuals or in teams to complete this ultra-long distance triathlon.

Goodwood Motor Racing Circuit in West Sussex will play host to this brand-new event on Sunday 8 August 2021, with the traffic-free circuit providing a stunning setting for this unique challenge.

The swim will take place in the nearby Westhampnett Lake, with the bike leg seeing participants complete 52 laps of the circuit and the run comprising of ten laps through the paddock and pit lane and around the circuit’s perimeter.

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.”

As well as individuals, teams of two, three or four members can take on the challenge together with the freedom to choose how they split up the swim, bike, run distances between themselves.

The 5km swim is made up four 1.25km laps, the bike laps are 3.8km long, and each run leg is 5km, giving plenty of opportunity to change between team members. The only conditions are that the changes between members can only take place in the designated area at the end of the laps and each bike stint must be a minimum of 10 laps.

Several British Triathlon affiliated clubs have registered teams to take on the event, with the organisers providing examples here of how teams can divide up the 255km.

Commenting on the relay option, Dowle, said “After launching 255 Triathlon at the end of last year, we sat down and discussed how we could open the event up to a wide range of athletes of all abilities and including both long and short-course athletes.

“We have devised a unique new relay format which will not only make the event more accessible but will also create an amazing atmosphere of team spirit at Goodwood on race day.

“This new relay format will allow long-course and short-course athletes to come together to form teams with each team creating their own unique race format. We’re very excited to see how teams decide to tackle the event and the tactics used to complete the 255km course in the fastest possible times.”
