Rode most of the way home last night, before I gave in and got on the metro. I rode about 12 miles, and it took 80ish? minutes, for an average speed of 9? miles per hour? Only had to walk on 2 hills, but I was on and off ice every seemingly every few feet, which was kind of exhausting.
What finally caused me to give in, though, was that once I hit the 'outer suburbs' (Falls Church), most of the MUP was packed snow/ice covered. Prior to that (Arlington), it had been somewhere between 'half clear' and 'more clear than not', though still plenty of ice to contend with. It made me wonder if Arlington actually does some clearing on the Custis Trail, because I would have guessed it was shadier than the stretch of W&OD through FC. Perhaps, though, it is the heat from I-66 that helps? Of course, at least one rider passed me on the snow/ice which makes me think I just need to develop more style - but when I tried to keep up, I felt way too unsteady.
Either way, I think I need to reconsider my cycling options surrounding snow times. I don't know that I'm ready to be a committed snow rider -- I find it very nerve wracking. And my street options aren't so good once I leave DC, though I suppose I could explore possibilities in that regard.
