Whether you call it a Gobble, Turkey Trot, or Thanksgiving Day race, it is a tradition that goes back a long ways. According to Wikipedia, the Buffalo, New York Turkey Trot race, established in 1896, is the oldest continually running public footrace in North America.
Many courses used for these Thanksgiving events are run at major certified USA Track and Field road race distances between 5,000 and 42,195 meters. Some organizations hold their Turkey Trots the week prior to Thanksgiving in order to provide festive holiday meals to homeless and low-income families in their community. Turkey Trots range in size from just a few dozen runners to tens of thousands. Most Turkey Trots benefit local charities (1).
