Another similar event would be the Amtrak Century put on by the OC Wheelmen.
http://www.ocwheelmen.org/page/show/...amtrak-century You ride from Anaheim train station down to downtown San Diego and then take the amtrak back up.
I'm not sure when registration is this year but it tends to sell out in about 15 minutes flat. Be ready. The ride is usually in September.
