Course details are specified for each distance. The Olympic bike course ascends and descends Santiago Canyon and lists an approximate total elevation gain of 1,738 feet. The Sprint bike course remains near Mission Viejo and the run courses use trails and surface streets around the lake. Aid stations are roughly every mile on the run course, with specific aid stations noted near miles 1.5, 3 and 4.5; each station will include a restroom. The swim exit is about 300 feet from Transition 1. The duathlon starts at Transition 2 and finishes at the lake.
Registration is offered in package tiers. The basic package includes timing, a finisher medal, pre-assigned bike space, post-race food and souvenir merchandise.
