4 mile run / 53.4 minutes

Hey babe...it's your wonderful, exhausted wife ;) just finished my 4 miles in 53.4 minutes. First mile was 13.2 minutes; everything after that is a blurr! Totally pooped...my heart rate stayed in the high range (172 BPM) almost the whole run. I felt good though...if you call good; sweaty, achy and exhausted :)
