Run for Central Park

I didn't expect to feel that great this race as I only ran once all week and my lower back was sore from lifting the day before.  After the second mile of the four mile race I got a side cramp (haven't had that for a long long time) and I think it was partially due to my back being so stiff.  I was running right around a 6 min per mile pace but slowed down the last mile and a half with the side cramp and stiff back bothering me.  I can also feel I'm losing endurance only running one or two days a week the last 3 weeks now, here is the RESULTS.
