Believe it or not, Thanksgiving is one of the most popular running days of the year. In 2015, 901,753 runners completed Turkey Day races—and that’s not even counting all the people who ran Turkey Trots and similar races on the days immediately preceding the holiday.

What makes Thanksgiving such a popular day to run? Well, preemptively attempting to run off all the calories you’re going to eat at your Thanksgiving feast seems like a pretty solid life choice. Plus, these races come with some great perks, from complimentary apple pie to diamonds (yes, diamonds). Check out the 20 most fun Turkey Trot runs we found across the country.
