More About the Course

This is an out and back course, meaning you will begin and finish in the same location.

Our courses are not closed, which means that there are often runners, walkers, and others enjoying the day along with you. Safety is must and all runners must stay on the right side (pedestrian side) of the beach path. The course never goes off the beach path.

On-course support: Courses are well marked with two water stations and restrooms along the way. Turns will be clearly marked with chalk, a sign that says runner turn, and a flag.
