Mark it in the books, we have another racer in the family. My son completed his first 5K road race today, and he enjoyed every mile. We ran until he needed a walk break, then we walked until he was ready to run again. Rinse, repeat, finish line, banana. The last mile was mostly walking because when he runs with me he only goes about 2 miles, but he claims that he is ready to do another. Since he was three I have been waiting for him to be old enough to run 5K races with me, so he made my day.
