Idaho’s Ugliest Sweater Run, brought to you by The Dirty U

Idaho’s Ugliest Sweater Run is a Saturday morning 5K in Boise, starting and finishing at Payette Brewing Company on South Pioneer Street. The Dirty U organizes it, Payette Brewing Company sponsors it, and the theme is right in the name: runners participate in a holiday run built around ugly sweaters rather than a serious race-day image. Registration is available for single runners and teams, with price breaks for groups of 4 to 9 and larger discounts for groups of 10 or more. The entry waves use holiday names — Jolly Joggers, Santa’s Sprinters, and Snowflake Striders — which indicates the event is aimed at social runners, friend groups, and people who want a December 5K with a brewery base.
