I vote for all of the above for options. Try some hiking, unpaved trail running if available to you. I don't care for the recumbent trainers myself but would recommend some of the spinerval etc videos that are out for some motivation while indoor training. Looks like your in So Cal though so riding at night is a great option - not always so pleasant here in the Midwest winters. Get a mnt bike and ride trails at night with some good lighting its a blast.
