I had a great experience for my first IM 70.3, with perfect weather. The lake was warm and the swim was pretty crowded - wasted plenty of energy dodging/running into fellow triathletes. The out-and-back bike course exposed my lack of training on the bike.. impressive splits by the Pros. The run was easier than anticipated but I developed a muscle cramp, slowing me down a bit. Overall very well organized and inspiring to improve. Volunteers did a fantastic job.
