OMM

This month's programme covers the OMM - The Original Mountain Marathon - in Highland Perthshire. The first multi-day event of its kind and to many competitors, still the best. A test of endurance, navigation and willpower where competitors need to carry everything they need on their back.

It will be available for the rest of the world on BBC IPlayer.
