The course is well-marked – with a combination of blue ribbons, blue arrows and flour used to draw directional lines on the ground. However, know that there are MANY intersections and runners are responsible for staying on course. To ensure that all runners stay on course and run the entire trail there are three checkpoints on the course – in undisclosed locations. Each runner must pass through all three checkpoints or they will be disqualified. If a runner goes off course he or she is well served in going back to the original spot where they left the course – or they risk missing a checkpoint and being disqualified.
