An off-road running race held in the north-western foothills of Camp Pendleton with a start/finish at Camp Las Pulgas.  The course offers multiple distance choices and includes a challenging hill climb followed by scenic views of the surrounding mountains and meadows.  

The Cross the Floss kid’s run, sponsored by Pendleton Family Dental, is in the venue area which gives Heartbreak Ridge participants a chance to cheer for the kids and make their experience rewarding and fun!

This is a great opportunity to bring out the entire family and your friends to take advantage of the various routes available.
