South 100 - Whythra Bys Vyken 100 milers
South 100 is a team based, self navigated 100 mile trail event in Cornwall. Teams consist of five runners who start together and are supported by a crew for the entire event. The organiser currently offers three route options: Bude to Gwithian, Coverack to Porthtowan, and Mount Edgcumbe to Coverack. The run must be completed within 36 hours.
Entrants must meet qualifying requirements: prior completion of a 100 km event in under 20 hours and prior experience of night running. Each runner must provide an emergency contact able to collect them if required and must be dropped off and collected from the event base in Camborne. The crew meets teams every 5 to 6 miles and will transport runners around any ferry crossings where necessary. Participants may bring one box of gear or food (50 x 50 x 40 cm); a box can be provided if needed.
Support provisions include water, Pepsi, sweets, crisps and simple hot food; runners must supply their own primary nutrition. Medical incidents will be managed by qualified first aid personnel on the crew. A tracking app is used to monitor progress. Entry is priced at £110 and is non refundable. Finishers receive a Whythra Bys Vyken 100 miler buckle. Weather warnings from the Met Office at amber or red levels prevent the event from going ahead and may lead to rescheduling or a virtual event.
