Notes
Easy Run (7:27 pace p mi adj for heat)
As I was about to take first step and wince in pain, noticed my Garmin had run out of juice (it said 61% of battery 2 min before!). So measured this "old school" (Gmap pedometer) and used my iPhone time. First 100 yards Psoas and upper groin hurt like hell (hobbled and yelled) and magically began to subside. Felt twinges of pain at various times. Started to feel the heat around 4.5 miles in and "stretched" it to 5.5 miles before a walk break. Final segment back to Y was very easy (towards end Psoas started to hurt -- stopped for a sec - then resumed & it felt ok).
