The island of Tiree; 11 miles long, 6 miles wide, famed for it’s white sandy beaches, blue skies, unspoilt landscape, and no midges! Tiree’s coastline is rugged, beautifully carved, and adorned with long stretches of firm sandy beach. The complete circumference takes in 35 miles of the finest Hebridean scenery. And that is the Tiree Ultramarathon – The Land Below the Waves.

The route will start and finish at Scarinish Beach Hotel by the harbour. Coming out of Scarinish you'll head clockwise around the island to eventually cross your last beach, Gott Bay - the longest of the 14 beaches you will visit. This legendary event has been known to test the bravest runners. Hail, wind, rain and even snow has lashed across these sands. But more often than not Tiree is bathed in bright sunshine. Whatever the day brings, your ultramarathon journey will definitely be one to remember:
Race HQ will be at The Scarinish Hotel all weekend. There will be live music and celebrations well into the evening. Full details and timings will be sent out nearer the time. It's going to be an amazing weekend. See you on the beach!
