Ironman Louisville 2010 was going to be hot. We all knew it heading into the morning, and my first step outside my condo confirmed it — Sunday was going to be a true test of execution, nutrition, and mental skills. By mid-morning the sun was in full effect and it was bearing down on the racers. Combined with the humidity, it was an evil 1-2 punch that didn’t go away until some clouds rolled in around 6pm. Riding had a slight cooling effect; but it wasn’t helpful as most folks didn’t realize just how hot it had become started running!
