This race is pretty great! It is very well organized and there are soooo many volunteers. You can drop your running bag off that you won't need by the race start line in a trailer where they keep track of it by numbers that they will hand you. There are many different waves that start the race at different times but a lot of it is weaving in and out of people at the beginning therefore don't expect a PR. It is more for the experience itself. The public do cheer you on as you run right through their neighborhood and there are also bands along the way as well for sweet music. The finish line is in the CU football stadium which was awesome. Since the race is so big for Boulder and it is in a downtown area there aren't as many places to park. The only downside is really all of the people can be a bit overwhelming during the race, after and before.
