While this could be a lesson in the importance of pre-planning...I actually think it's good I'll be running in the hottest conditions in days. If you can't avoid the difficult conditions, then at least you can attack them head on. While it's certain to be a slow and terrible run in an hour or so, I'm ultimately feel much more accomplished than if I had postponed the event for a more comfortable time. The expression "comfortable with being uncomfortable" comes to mind in this situation...a phrase borrowed from the armed forces, and Clint Hurdle.
So today's a full reverse from last week. I'll immediately regret this decision shortly, but at least I'll be training for the worse.
