It is approaching noon on a Sunday and the temperature is about 90 degrees. Or at least it feels like it. There are thousands in line to run today and they will release them in groups of about 15. The starts are about 5 minutes apart to allow separation to occur on the course. It will take most of the day to clear the backlog of those awaiting their start. The run is 5K or 3.1 miles with obstacles. This is a difficult day.
