It’s 12 days from the marathon and taper paranoia is setting in. It doesn’t help that it’s been pouring rain. I worry with every step that I’m going to slip and fall down on wet pavement. I stare at my feet as I walk, dreading an ankle roll or a knee twist. On the bus, I shrink back as the girl in front of me hacks and coughs. Can’t I just work from home for the next week and a half?
