I'm not rehabbing an injury or anything, but I plan on some structured indoor workouts this winter. One thing I'm looking forward to (in a masochistic way since I did the tour in 2013) is the Tour of Sufferlandria. The Sufferfest makes a fantastic series of videos for those days when you're stuck on a trainer, and the tour is a brutal test of endurance that I'm hoping will prepare me for a 200K in the spring.
