I dropped 35 pounds from riding/eating right, but have put about 5 pounds back on this winter. Its hard around the holidays to not join in and eat, plus some other things I do that seem to center around eating.
I used a trainer when the weather started to turn, but I haven't been on lately. It is just too boring, and I've always found that getting back on the road does more in a week than the trainer does all winter long.
As long as I remain steady until around March I feel like I'll be OK, I know once I start riding again the weight will come off.
