I am in week 6 of marathon training. After not having ridden for a couple of weeks, I rode 28 on Monday. I think it affected the rest of my week, because my Tues., Wed. and today runs were all three kind of "mehh." I am hoping it is just a phase. Other than that, I am so joyful to be out running in the winter. It's a good way to see holiday lights and other sights.
