Note: You must register in advance for this ride, there is no day-of-event registration.  Registration closes at noon on the Thursday before the ride.

This ride is a modification of the old Triple Loop 400k.  It makes extensive use of the area river trails, including the SART, the SGRT, and the Los Angeles/Rio Hondo Trails. 

The ride starts at the Extended Stay America in Yorba Linda, and makes its way over to the Santa Ana River Trail and a fast morning ride down to the first control in Huntington Beach. The route proceeds through town to PCH and along the coast to the San Gabriel River Trail in Seal Beach, and then follows SGRT through the Whittier Narrows and over the Santa Fe Dam to the second control in Azusa. Along the trail there are spectacular views of the San Gabriel Mountains. The path is retraced from Azusa along SGRT to Encanto Park (where water and restrooms are available) and then to Monrovia where the route heads south, following the Rio Hondo and Los Angeles River trails to Long Beach. This part of the route mostly follows river trails and is fairly flat so it is possible to build up a good time margin. There will be a headwind on either the northbound (SGRT) or southbound (Rio Hondo/LART) leg (and likely a tailwind on the other.)

The route continues through Long Beach on the beach trail, then over to PCH and down to Laguna Beach where it follows the bike route through town. The route returns to PCH for the ride down to Dana Point and diverts to the bike path through Doheny State Beach. Note that there are many restaurants in Dana Point slightly off route. The route then proceeds down the old Coast Highway to San Clemente, where your navigation skills (or your bike computer's navigation capabilities) will be tested on the elaborate bike route through a beautiful residential neighborhood, interspersed with abrupt turns and sudden steep hills (sometimes in combination.) It then continues down the Old Pacific Coast Highway through the Trails State Beach campground (where there are numerous restroom facilities with water taps) and follows the trail through Camp Pendleton to the control at Las Pulgas Road. Returning along the same path to Dana Point and Doheny State park, the route diverts on a loop through San Juan Capistrano, Mission Viejo, Irvine, and Newport Beach before rejoining the SART for the return to Yorba Linda. Food will be provided at the end of the ride.

This is a minimally supported ride: Riders are responsible for finding their own water and food out on the course. There is no SAG vehicle.

All participants are required to have working front and rear lights on their bicycles and meet the reflectivity guidelines as required by Article 10 of the RUSA Rules for Riders.  An inspection will be conducted to ensure compliance for your safety during the ride.
