Mike, I watched your video yesterday. I could hear the disappointment in your voice... but for you to make the switch to the half is completely understandable at this point. You should also be MEGA proud for raising well over $5,000 for your charity! You share an important point that endurance events are not easy. They require dedication, heart, and sometimes a whole lotta LUCK just to get to the starting line! Here's wishing you a happy and healthy half marathon!
