My hip flexors were kind of sore starting out, but felt OK after a half mile or so. It was a little cooler this morning than yesterday with the clear skies, but the birds were singing and spring was in the air. I pushed it a little harder than yesterday after the first mile and I started to feel a little stiffness in my right knee towards the end. I think I'll first try to get back to running every day before I increase the mileage much. |
