12 Mile Road March
The Sapper Leader Course 12 Mile Road March route is one of the most rigorous routes used by the Force. The 12 Mile Road March is an entrance requirement that must be passed prior to gaining acceptance to the course. It is held at 0300 on day one of training, the first day after the ATRRS start date. There are no retests authorized, because it is an entrance requirement. It begins and terminates at the Sapper tower on Training Area 147.
The difficulty of the route does not fall on the length but the dramatic changes in elevation throughout the route. The most grueling changes are the infamous "6 mile" and "8 mile" hills.
