Sounds nice - Have fun!
I am more of a casual bike rider, but many of my friends like to do a ride up the coast either part of the way or all the way to Oceanside, then return the same way or take the train from Oceanside to Solana Beach and ride back from there. The ride to Oceanside is about 26 miles. The hill at Torrey Pines State Reserve is challenging on the way back.
For a casual bike ride, start at WindanSea and just go south through residential areas until you reach Pacific Beach and Mission Beach where you can ride on the "boardwalk" along the ocean. It goes all the way down to the end of the peninsula, and you can either ride back the same way or ride along the bay side (Bayside Lane).Edited: 10 July 2018, 08:01
