An exciting, challenging, fun, and a little bit bonkers off-road event set in the heart of the Cairngorm National Park. There are two courses to choose from, both are based on Loch Morlich, with its superb water quality, and the beautiful Glenmore Forest. In 2015, the race is proud to be hosting the Scottish Cross (aka 'off-road') Triathlon Championships.
