Test your navigation and strategy by entering one of the five off-road adventures we have organised. Using a waterproof 1:25,000 OS map which we provide, navigate trails and hills on foot and bike to collect as many check points as you can in the set time. You plan your own strategy and route, deciding how many CPs you want to visit and in what order. You will lose 1 point for each 30s you are late coming back. All checkpoints are worth 10 points each. Distance covered depends on how many checkpoints are visited, and depends entirely on your level of fitness, as well as your running/biking and map reading skills.

4 hour LONG Adventure Race - 4 hours, navigate to as many checkpoints as possible within the time. Starting on foot, there will be one transition to Mountain Bikes.
