The Calon Lân 300 is a 300-mile ultra along the legendary Cambrian Way. Expect 74,000 ft of climbing, spectacular Welsh landscapes, and 7.5 days to complete an unforgettable non-stop journey across the wild heart of Wales..
Starting in the north and finishing in the south, you’ll traverse epic landscapes, from the towering peaks of Eryri National Park through the wild hills of Mid Wales, and down into the rugged mountains of Bannau Brycheiniog National Park.
