Get fit, lose weight … New Year's resolutions rarely last. A week into January and most of us are already wavering in our promise to work off that Christmas turkey. What's needed is a little inspiration to keep us going. Adventure holidays can do just that by putting fun at the forefront of fitness. Why pound the treadmill when you can run in the Himalayas? Why stay static on a fitness bike when you can cycle amid splendid mountain scenery? Or lap the pool when you can swim the Caribbean? Stick to your New Year's resolutions with one of these adventure fitness trips.
Mountain bike the Yukon
Swap static gym bikes for the wide-open vistas of the Yukon Territory in a new mountain biking trip to the wild north-west of Canada. Pedal through gold rush history and the land of the grizzly bear on more than 800km of mountain trails that surround the region's capital city of Whitehorse. Stay in luxury yurts, and dine on home-cooked Yukon food and locally brewed beers.

This new trip on the northern section of the Scottish Sea Kayak Trail – Europe's only long-distance sea kayak route – explores the wild, unspoilt coastline of Scotland's north-west coast.

Freedive the Red Sea
Freediving conditions the body and relaxes the mind, as you focus on holding your breath underwater rather than relying on scuba gear or a snorkel.
