My daughter and I have participated in this run for both years.  Colonial Park is really beautiful and the Girl Scouts really go out of their way to make it a fun time for everyone.  Great goodie bag, live music, games, lots of food and a very cool park for the kids to play in.  Parking was super easy this year.  Run is pretty flat... just feels long because both years the sun has been out and it gets hot.  But everyone has fun.  Great, great family time and a fun run to do with your daughter!
