This is my biggest race pet peeve. Almost every race I enter starts well after the advertised time. If they say 8:00, figure on 8:10 at the EARLIEST. Sometimes even later than that. It's especially irritating this time of year, because every minute you delay the start, the temperature goes up another degree or two. The past two weeks, I've run races that each started over 20 minutes late.
THIS MAKES ME CRAZY!!! Why on earth can't races start on time?
