The route hasn't been posted yet but I hear it's going to be the same as last year. La Jolla, Lake Hodges, Couser and Rice Canyons, Fallbrook to the coast and back south to La Jolla.
If you want to do a double metric, this is an excellent route. This was one of my three favorite rides in 2007.
The entry fee is $10 which gets your card punched, some water and limited SAG.
