I didn't have anything in the way of mileage goals other than to ride more than I have in the past - typically 1,000-2,000 miles per year. By riding the trainer through the winter, which I historically haven't done, I'm about to hit 1,000 miles on the year already. So far so good on that front.
The other goals were to get my butt in shape and give racing a go. I've lost close to 30 lbs and I'm probably in better cycling shape than I've ever been in through the trainer workouts. I've been in two crits and gotten shelled in both, but saw improvement in the second one and am looking forward to continuing to improve. The only real racing goal I had was to be able finish with the pack by the end of the year and I think that is within reach.
