Welcome to Whythra and its prestigious 100 Miler Trail Race, an epic adventure through Cornwall's stunning landscapes. This unique challenge brings together teams of five runners who embark on one of three carefully crafted routes: Bude to Gwithian, Coverack to Porthtowan, or Plymouth Sound to Coverack. To qualify for this grueling event, participants must have completed a 100k race within the past year and finished it under 20 hours. Additionally, each runner should be experienced in night running as part of an organized event. The organizers aim to assemble teams based on individual capabilities, ensuring that all members are well-matched for this endurance test. Safety is paramount at Whythra Bys Vyken 100 Miler. Each participant must provide emergency contact information and a kit list including essentials such as waterproof gear, hydration systems, nutrition supplies, first aid kits, bivvy bags, headtorches with spare batteries, and more. The crew will transport runners between checkpoints every five to six miles, ensuring they are well-supported throughout the 36-hour event. The race is self-navigated by teams who start together from a base location and aim to complete their chosen route as one unit. Crews provide water, Pepsi, snacks, and hot food at intervals along the way. Participants can bring an additional box of gear or supplies (50x50x40 cm) if needed. In case of medical emergencies during the event, trained staff will handle all incidents promptly. However, should a major health issue arise that requires immediate attention from outside resources, the race may be canceled to ensure the safety and well-being of participants. The cost for each runner is £110, which covers entry fees but includes no refunds unless positions can be filled by replacements before the event date. Those who successfully complete this monumental challenge will receive a coveted Whythra Bys Vyken 100 Miler Buckle as recognition of their achievement. Participants must adhere to strict safety guidelines and agree to all terms and conditions, including waiving liability for risks associated with trail running in challenging weather or terrain conditions. The event may be postponed or canceled if severe weather warnings are issued by the Met Office. Whythra Bys Vyken 100 Miler offers a remarkable blend of physical challenge, camaraderie among teammates, and breathtaking Cornish scenery, making it an unforgettable experience for seasoned trail runners seeking their next great adventure.
