The Three River Challenge in South Kyme
The Three River Challenge is a 15 mile (14.7 mls / 23.65 km) riverbank and road run along the rivers Slea, Skirth and Witham. The route combines trail running and road running across the Lincolnshire Fens and includes areas of rough ground where extra care is required.
The assembly area is the Coronation Hall in South Kyme village. Free parking is provided on a grassed area behind the hall and additional parking is available along village roads.
Entry options list adult runner and adult walker at £17.50 each; entry on the day is available up to one hour before the runner start at a cost of £20.00.
The course is marshalled at decision points and where needed to reduce the risk of traffic on public roads. There are three drinks stations at approximately 7 km, 13 km and 17 km. Results will be displayed electronically in the assembly area and published online once ratified.
After the event participants will be offered free hot soup, tea and coffee, cake, and medals. Bags may be left in the Coronation Hall under supervision, though the organisers do not accept responsibility for loss of personal items. Toilets are available with limited changing facilities. Dogs may accompany participants but must be kept under close control.
Entering and participating is at participants' own risk. Participants confirm they are medically fit, agree to follow safety rules and marshal instructions, and acknowledge the organisers are not liable for death, injury, loss or damage arising from participation.
