An overgrown path in Perthshire - just one of the obstacles on the TGO Challenge Life is a challenge but some people enjoy physical challenges in the outdoors. These challenges can be very rewarding and you can feel a great sense of achievement in their completion which can spur you on to do more and set yourself new targets. People are very different in what type of challenges they want to do and this can vary from just completing your first Munro (a mountain in Scotland over 3000 feet), walking the Skye ridge in 24 hours, doing a more organised challenge such as the TGO (The Great Outdoors challenge) or competing in an extreme triathlon. Much depends on whether you like to set your own individual goals or prefer the stimulus of a bigger group and whether you are competitive or not competitive.
