From Fort William to Inverness, the 77.5-mile (125 km) Great Glen Way follows the Caledonian Canal. Traversing slopes above Loch Oich and the legendary Loch Ness, it also passes Ben Nevis, Britain's highest mountain.

The path gives mainly low-level running on well-constructed paths along canals, an historic railway line, forest tracks, loch shores and open moorland.

For those looking for a greater challenge, the high level option from Invermoriston has some steep climbs through wooded hills before re-joining the main route, all set against the dramatic Highlands backdrop.

The Great Glen Way is one for those who want decent running paths and great scenery, without severe gradients. Ease of navigation makes it suitable for both experienced trail runners and newcomers.
