The article says:
Due to Friday's flood in Manitou Springs, events initially scheduled in the town's parks will be moved to Memorial Hall in the back of city hall.The events include registration and scheduled festivities.
I am assuming that registration is packet pick up. No expo this year which is a bummer, but completely understandable. I don't think they will change it in the info booklet since it is the same for every year and not something they change just for one year. My advice is to look for all the crazy runner types wearing a fluorescent yellow or purple/blue wristband and ask them where they got it ;) Good luck this weekend and have a great race!
