NPS Race Rules:  This race takes place in the National Park Service's jurisdiction.  Please familiarize yourself and comply with our NPS Race Rules.

Special instructions: This race uses an unusual age-handicapped format, in which older runners start early and younger runners start late.  There are approximately 20 separate start times, which are based on age-group records for men and women.  Winners of the race have ranged from teens to 50-somethings, both men and women.  All runners receive prizes since all participants are encouraged to contribute unique used items to the prize pool.  Past prizes have included 1970s baseball cards, a Simpsons dart board, a New Guinean sheath.  More conventional prizes also are awarded, including cherry, apple, and blueberry pies in commemoration of the nation's birthday. 

Volunteers:  Yes, please volunteer!  We always need volunteers, including friends and family who accompany runners to the race.  Volunteering to serve during the race (thereby not competing) fulfills the requirement for getting a Bunion Derby award. To volunteer, contact race director Lauren Bullis.
