Ran well this morning for an hour and a half. Knees groaned a bit at one point, not really sure whats going on there. Walked for an hour this afternoon but held off on the run. I want to see if this knee thing is going to persist. Met a guy who lives just up the road and he introduced me to a little stepwork he includes into his routine, 89 steps up and then down – thats definitely going to help.
