Hot weather?

Ran the Psummer Psycho loop yesterday(15 miles-3 hrs). I have no idea why. It was super muddy and hot. Ran out of water after about 10 miles and the hydrants are still shut off. Slowed way down the last 4-5 miles. It's strange how hot 65 degrees can feel after a winter of frozen runs. It's 70 degrees now. Think I'll go for a ride.
