Event information
Duathlon Race Routes
Run 1: Competitors will start under the main gantry near the Tavern restaurant. The route goes out onto the main circuit in an anti-clockwise direction to the turn point. After turning, competitors complete a full lap of the track in a clockwise direction before exiting via the pit lane and following it down into transition.
Bike: The bike route is 7 laps in a clockwise direction around the track. Please note that you are responsible for counting your own laps - plan how you will do this to avoid mistakes on the day. The timing system will count laps and anyone not completing seven will be disqualified.
On completing the final lap, competitors will turn sharp left back up the pit lane and into transition – please take extreme care at this point of the course and ensure you brake early as advised by the signage.
Run 2: The final run is a lap of the perimeter track, with the finish left under the Avon Bridge and then right for the red-carpet run to the finish line.
The super- smooth Castle Combe race circuit is ideally suited to all levels of racing with it's wide, predominantly flat course making it ideal for draft-legal duathlon racing. Please note, following your feedback from the 2024 event, an additional technical turn will be added to ease congestion on the track from bunched up riders, increasing competitiveness for those looking to qualify for the World Championships.
Bike Route Rules
There are certain rules you must follow when on the bike route.
Even though the route is traffic-free, you must be aware of others around you at all times.
Helmets MUST be worn at all times you are in contact with your bike, including in transition.
