I'm going to go for 250 miles this month.
The roads are salted and the temps are going lower all the time, so road miles will be few. The rollers will surely get a good workout and that's where the lion's share of miles will come from, unless the weather drastically changes.
Hey, it's only 20 days till the winter solstice, then the days start getting longer. It might not warm up for a while, but more daylight is a GOOD thing!
