I did more all-out reps of 30 seconds on the trainer this winter, which I've always hated and avoided before, but it seems like that's paid off a little. On my first few outdoor rides of 2013 when I've timed stuff, I'm just as fast now on some of the easy to medium local climbs as I was last fall (haven't timed any of the harder ones yet). Actually got a PR on one Strava segment climb on March 30 without making a special effort to hammer it, and it was the first time I've done that climb since November. What kills me after spending a few months mostly indoors is headwinds - especially chilly headwinds. My cold weather clothing is very loose and catches a lot of air, which is part of the problem, but sustained effort into the wind also isn't something I've found a way to prepare for indoors. Maybe I just didn't go to the drops enough on the trainer and have to get used to the position again.
