Tiree Ultramarathon

Set on the Hebridean island of Tiree, the Tiree Ultramarathon is a 35-mile coastal loop around the island. The course starts and finishes at Scarinish Harbour, with racers following a series of checkpoints and simple navigation aided by route arrows and the event team. The anticlockwise route tracks firm sandy beaches, gravel tracks, dunes, grassy paths, and occasional rocky sections, always with the sea on the right. Features include a course map, medal, tech T-shirt, and goodie bag, plus a prize-giving and an island ceilidh on Sunday. Runners can enter as individuals or in 2- or 4-person relays; there is a 10-hour cut-off. Visit the organization's website for the most recent information.
