Umm puffing a bit! Legs are hurting also. Uncomfortable chest which really plays on my mind. But I did it can't say I enjoyed it as much as other runs but they can't all be great. Can't run again now till Thursday. Once my chest/heart paranoia subsides I'll be at it again. Again last stint felt a bit lame but 3 minutes!!!!! Last time I ran that much I was chasing the ice cream van!
