hitting the mileage, but definitely not the pace

running shoes with orthopedic insoles-check; asthma inhaler-check; iPhone loaded with run-inspiring music-check; 90-minute run as scheduled on training calendar-check; acheiving minimum pace required to not get scooped up by the loser bus at the Chicago half--check box left blank----WTF is up with the heat and humidity in the Midwest?????? I'm hoping September is officially Fall and not the dog days of Summer!
