I was in coral A, started maybe 10 feet from the front of the pack, and the first mile was a bit packed. It is like that for almost every half I've done. You always have people starting slower than they should for where they line up and having a turn so close to the start (within the first mile) doesn't help because too many people pinch over while making the turn.
The roads are wide though and it didn't take too long to get through the crowds and get into your normal pace for the first 5K of the race.
It used to be on the waiver up next to the number, have they removed it?
The A runners experience with crowds and the C runners experience is very different... As well it should be. It is still a lot of people with some very narrow spots.. Starting at the front and running a fast pace is much eaiser than thrying to come from the back to post a fast time.
It isn't on the waiver. Only the number is on there.
