That always happens. People don't realize that "fun run" doesn't mean "wander around like an idiot". Couple weeks ago I did a 10k. We were supposed to start at 8:15, with the 5kers starting 15 minutes later, but didn't get off until 8:30 because literally thousands of the 5kers were socializing in the street IN FRONT OF THE STARTING LINE. The race organizers had to get a couple of motorcycle cops to herd them away because they wouldn't listen to the announcements to GTFO. Totally destroyed my warm-up prep. Of course after we finally got going I had to wade through fatties, walkers, families, and other casuals for a quarter mile, because they all just had to start at the front. grumble grumble
