About this race

The Pigtails Run - "The Flat Fat Ass" marks its 20th year in Maple Valley, WA, presenting a cheerfully unconventional take on endurance running. The event fosters a lighthearted, slightly silly atmosphere, establishing it as a distinct part of the local racing calendar. Participants will follow a pleasant riverside, wooded route. The mood frequently evokes "It's Beginning to Look Like Christmas" for those who lean into the festive, quirky spirit. With modest aid stations, this race prioritizes the experience and fellowship over achieving personal records.
