Our ever popular kids challenge is as follows. Ages 4-7yrs Up to 2km with up to 20 obstacles, 8-10yrs Up to 3 km with up to 20 obstacles. 11-13yrs Up to 4km with up to 24 obstacles. Difficulty increases with each age category. One parent is allowed to shadow along (no charge). This is a challenge and NOT a race, anything they cannot do, they can go around. Medals are given only at the finish line. There are no participation medals. They EARN it.
