There is a ton of interesting history for this event over the past 18 years, but only two facts that are truly important. First, only two runners have participated in all 18 events so far--me and another guy. Second, I have more "Riddle Run" miles than anyone on Earth (427 miles). I'll keep my streak alive and add to that total in a couple of weeks.
Here are the Riddle Run winners from the past 18 years. The Riddle Run 28-mile course records are 3:39 (men) and 4:18 (women).
