Endurance events company, Fullsteam has launched Castle to Coast, the UK’s only sportive triathlon that will take place between Windsor and Brighton on Saturday 10th August.

The innovative, non-competitive format is designed to break away from the obsession with time and racing, instead providing a relaxed, inclusive event that focuses on the adventure of the swim, bike and run.

The Castle to Coast challenge, limited to 500 for the inaugural event, includes a 1.2 mile swim at Eton Dorney followed by a 67 mile open road ride through the picturesque but testing Surrey Hills and a 13.2 mile run up Ditchling Beacon and over the South Downs.

Lee Brown, Director and Founder of Fullsteam says: “In 2019 we wanted to create something new in the world of triathlon. Castle to Coast’s sportive format will appeal to those looking to step up to a middle-distance triathlon without the pressures of racing and beating the clock.”

Triathletes can enter from £140 via www.fullste.am and will receive a finisher’s medal, tech event t-shirt and free race photography. A team option is also available from £180 for three team members. Each member will tackle one leg and your own transport will be required to complete the partly self-supported challenge to Brighton.

The point to point nature of the event means that Fullsteam will be providing the opportunity for all entrants and their kit to be transported back to Windsor at the end of their challenge. Alternatively, bike and kit will be waiting at the finish line for all those departing directly from Brighton.


The start of the swim is just a short walk from the event village and transition area at Eton Dorney. At 8am on Saturday 10th August swimmers will start in the water, in waves, and complete a 1.2 mile continuous lap, exiting at the far end of the lake for transition. In an effort to reduce stress entrants will be allowed to start at any time within a ten minute start window.

The 67 mile ride is fully supported with a feed station, toilet facilities, mechanical assistance and marshals at key locations. Over 3,400ft of climbing awaits as the route takes riders through historic Eton town centre before taking in the Surrey Hills, an area of outstanding natural beauty and challenging climbs.

On completion of the bike stage, in the village of Hassocks, entrants will hand over their bike to the transport team who will transport it to the finish line in Brighton or back to the start in Windsor. Run bags and changing facilities will be waiting inside Hassocks Sports Centre before entrants head out onto the South Downs towards Brighton.

The 13.2 mile run section, along over 90% of fully marked trails, has a challenging start by taking entrants onto the South Downs Way and to the top of Ditchling Beacon. From Ditchling Beacon the route slowly descends through the countryside to Brighton.

A finish line party awaits on Brighton seafront where all finishers will receive their medal, finishers t-shirt and samples of Fullsteam’s new Recoverystak rapid post workout recovery drink. Free photography will be available via Fullsteam’s Facebook page in the week after the event.

Kit bags and bikes will be ready to collect for all those departing directly from Brighton. For all those heading back to Windsor the Fullsteam support staff will be on hand to take entrants to the organised transport.
