3 hr O' last week - no problem. Took it easy, then did did Dogs Tue, Feb 17, 2 mi in track at Sports Pavilion Lawrence Wed, the 18th, but at Thur's Dog Days over did the volleyball jumps. Ran one lap on level 3 of Allen Fieldhouse; next time pain in right calf stopped me from running and didn't bother to walk any more.
Took so long to recover and tried to start back running too soon. ART and stretching exercises from Rob Jones were right, but didn't gauge how serious the strain was. Before next long run in a hilly area, allow more time to recover.
