They say Arran is Scotland in miniature. From dense forests and coastal scenery in the South to crumbling castles and dramatic mountains in the North, the Isle of Arran delights at every turn. Welcome to Ultra Tour of Arran – a 2-day off-road running adventure from Rat Race – the UK’s favourite adventure sports crew.

We do events differently. And for this one, we love the notion of setting sail to a location ‘over the water’ where you will feel a million miles away, but where you are in fact within easy reach of the mainland. With a simple 55-minute ferry crossing and a bundle of easy logistics thrown in, we encourage you to raise your clan and bring them over with you, enjoy our basecamp vibe, camp, run and be merry.

We know you’ll love Arran, and it’s not just the running. The island itself has a lot to offer with its own whisky distillery, artisan cheese, great food, history and a lovely ambience. And the running? Well, this wee piece of paradise has it all: Don’t let its size fool you though – packing a 50km Ultra each day over a 2 day weekend you will rack up 100km with serious vertical gain.The mountains are high, the glens deep, the forests enchanting and the coastal scenery stunning. Chose to do Day 1 only or the full 2-day Ultra Tour, operating from a central Basecamp location with all the trappings of a Rat Race event – good food, great amenities, friendly staff, Saturday night entertainment and of course, a well-stocked bar.
