Today may well have been the hottest day of the year so far. If it wasn't then it certainly felt like it. So perhaps not the best day for a lunchtime race.
And given my performance today perhaps I shouldn't have bothered. But bothered I did.
I went off too fast, blew up horribly 3 miles in, and limped the final two miles to the finish horribly slowly.
Back at the office I consoled myself by drinking a gallon of chocolate milk... It didn't help.
