Inaugural Ethos 8K Challenge Race + Ethos Grand Prix

On May 19, in Temecula, California, Ethos will push athletes to their limits with two demanding and fast-paced races. The Ethos 8K Challenge Race will test participants' skills in a fast 8K competition with obstacles and a course designed by former Navy SEALS. Following the Challenge Race, the Ethos Grand Prix will debut an exciting multisport competition that features a swim-run-swim-run race format consisting of 400-meter swim around buoys and a 2-mile run on a criterium-style loop course (swim, run repeat) offering excellent spectator viewing.

Throughout the day competitors will also be invited to test their stamina and skills against other elite athletes and members of the military and in a replica of the famous "O-Course" used to train the Navy SEALS for decades. A shorter, fun-filled obstacle course will be available for kids.
