Starting at 16:30 on the beach at Wells-next-the-sea, you head west towards Holkham Gap, where you join the Norfolk Coast Path and follow the same course as the Full and Half Sunset towards the finish on Snettisham Beach, 26.5 miles away. Can you also beat the sunset at 21:19? Don’t worry if not, as you have 7.5 hours or until midnight Sunday to complete your journey.
