Course format, services and awards

All races start and finish on the Thames Path next to the Wraysbury Skiff & Punting Club. Routes are out-and-back, lapped courses along the river Thames. The marathon comprises five 5.27-mile sections to Old Windsor Lock and back. The half and 10 km combine shorter out/back loops toward Staines Bridge with longer out/back sections to Old Windsor Lock. Distances allow for GPS variances.

Turnaround points are fully marked and marshalled. There are well stocked checkpoints at the start/finish and at Old Windsor Lock. Timing is by professional chip timing, bespoke Magna Carta medals are awarded, and podium awards are given for 1st–3rd male and female finishers. Race photographs are available for purchase within 24 hours. Medical first aid support is provided throughout the event. Visit the organization's website for the most recent information.
