If you would like to take advantage of the shirt option, it is $5, and can be added in the Swag area of your registration.  For those runners adding the shirt option, we ask that you register at least 10 days prior to race day, to be guaranteed of your shirt order. If you are within the 10 day window, we will ask you to pick up your shirt after the race, from the sizes available. We will do our best to accommodate all requests.
