I finally got back on the bike today. I did a short "inertia breaker" ride on Sunday, but today was my first day back at anything resembling training. I did a two hour ride in zone 2 with a 12-second superspin every 10 minutes.
Now I need to just keep doing that. Whenever I download a workout like I'm supposed to, Training Peaks puts a green square on my training calendar for that day. If I cut the workout short by more than 10 minutes, it's yellow. If I skip it altogether, it's red. Now I have one green square on my calendar for the week. My new goal for the season is to accumulate as many green squares as I can and I think the rest will take care of its self.
