Flattish Century from Carlsbad to South Laguna Beach, via Camp Pendleton:
~99 mile out-&-back, ~3400 feet of climbage (beware the afternoon cross-wind.) Bring your driver's license to get past the Pendleton gate guards and please obey the traffic laws and signs advising cyclists to ride single-file through Pendleton. It's a great route, but if enough of us civilian cyclists behave badly riding through there, the post commanding general can simply deny us access. (Pendleton is a military installation and is therefore NOT a public road.)
