Notes
Had to run the big loop in CP (added a repated on 102nd street transverse, puls to/from office) because of snow on paths. 4 loops. first loop not great, had to poop, 2nd loops stopped quick to pee. felt some tightness in left knee early on. just was worried and had to hold pace back. but on 3rd lap, felt cautiously good. on 4th, relaxed and it was my best loop by time. felt surprisingly good on that lap. of course, moments of fear and fatigue but no long periods of suffering.
