I did 8.6 and somehow found the one lone stretch of plowed bike path on an 18 mile stretch rail trail. The rest had about 2" of fresh snow and was not a great surface. Did most of my warm up on that but returned to the clear path and did 5X 4 min tempo. Paces off by 20 sec/mile compared to October. So either I'm out of shape, it was generally cold (18 F), or still feeling the effect of the head cold I have had for a week now. I think all three apply.
