The course is open to traffic; roads will not be closed and participants are responsible for obeying all traffic laws.
All participants receive one free local craft brew at the finish, an Ugly Sweater seal holiday ornament that doubles as a finisher medal, and an Ugly Sweater seal sticker.

Colorado Brewery Running Series merchandise including shirts, hoodies, hats, stickers, and drinkware will be available at the event. An Ugly Sweater sweatshirt may be added to ticket selections with size guaranteed if ordered by November 15.
The event permits dogs and strollers on the course with appropriate care and caution and notes that brewery and course policies may apply. Events proceed rain or shine and there will not be a bag check. Public parking is available and public transit may be an option nearby. A portion of proceeds supports local nonprofits.
