Wednesday lunch run

Do a few sets of straight and oblique crunches and some bridging exercises to work my core then a 30 minute jog. Legs feel heavy and even a slow pace feels difficult. That's what i get for stuffing up my back bending over in a field all last week so i can char grill my ass! My stride is shorter than it should be - i think due to the same tightness that's got my back feeling like it's meant to belong to the 80 year old me rather than me now. I try to stretch a bit after the run and have difficulty stretching my right hip flexor - that'd be part of my problem i guess but it's difficult to isolate.
