Cairngorms Loop Run — Route Guide & Guided Trips
The Cairngorms are the closest thing Britain has to arctic terrain: a high granite plateau above vast remote glens, where the weather does what it likes and help is a very long way away.
Loops here can be built at almost any distance. A shorter day takes in the Northern Corries and Cairn Gorm itself; a full day crosses the plateau to Ben Macdui, Britain's second-highest summit, and drops into the Lairig Ghru. Longer loops link Glen Feshie, Braeriach and the Lairig for a genuine wilderness ultra.
What defines running here is commitment. Once you're on the plateau there is no shelter, no phone signal in places, and the descent routes are long. It is the most rewarding running in Britain and the least forgiving.

Route notes and safety
Full winter conditions can occur on the plateau in any month. Carry more clothing than feels sensible, know your bailout routes, and treat the plateau in poor visibility as a navigation problem first and a run second.

Frequently asked questions
Is the Cairngorms Loop suitable for a first big mountain run?
No. Start somewhere with shorter escape routes — the Lake District or the Peak District — and build to the Cairngorms once you're confident with navigation and self-sufficiency.
How remote is it really?
Remote enough that a twisted ankle on the plateau is a genuine problem. Distances to a road are long, mobile coverage is patchy, and the weather changes fast.
What kit do I need?
Full waterproofs, extra warm layers, map and compass with the skill to use them, food beyond what you plan to eat, and a means of calling for help. Carry it even in July.
