Hmm, where have my cotton running gloves gone?

WOOOO HOOOOO!!! 15.5 miles done today at an 11:07 min/mile moving pace, in nearly perfect weather, finishing at 59*F and 44% humidity. If I could achieve that on race day, that would get me a 4:52 marathon! BUT I'm quite sure I can't hold that pace for another 10.7 miles, nor hit that pace if I count in some walking at the water stops. But on a perfect day, a sub-5:00 may still be within reach!!! And even on a not-so-perfect day, somewhere in the low 5:xxs is definitely probable. Details from Garmin to follow after a hot bath (nooooo no ice baths for me!)
And here are the charts and numbers that I know you've all been waiting for:

A fine finish!!!!
