Mountain marathons generally have two types of format and competitors choose which they prefer when entering the event. A “line” course requires visiting a series of checkpoints, usually between six and 10 of followed in a set order with the competitor choosing the best route between each checkpoint. The winner is the person or team with the fastest combined time over the two days. The other format is known as “score” and in this case the competitor has to choose which checkpoints to visit within a certain time. Different checkpoints have different points allocated to them. The objective is to plan a route so as to obtain many points as possible during the time allowed. Penalties will be imposed for overrunning the time allowance.
