  • Thrivent Turkey Trot
    Our motto: Run. Thanks. Giving.
    There is not a more perfect community to hold a Thanskgiving Day race than Burlington, Wisconsin. The course is picturesque, the people are friendly and the cause is just. The Thrivent Turkey Trot was started in 2011 and has become one of the largest Thanksgiving Day races in Southeastern Wisconsin. Proceeds from the race and a post-race turkey and pie raffle benefit the food pantry at Love, Inc., a local community service organization.
