  • NO LITTERING! This includes tossing your used water bottles. We have trash cans and recycle bins at each aid station, you may leave used water bottles there.  Just because it's a race doesn't mean you get to forget your manners and dirty our back yard.

  • If you choose to drop out please alert the nearest aid station personnel. We do not want to worry your emergency contact person!
