If you're looking to burn calories before the holidays or a fun way to train with friends, then Turkey Trot is for you. This event offers both 5K and 10K races, beginning at Crossroads at Silverbell Park. Both courses run along the beautiful Santa Cruz River bed. Take advantage of the opportunity to have your picture taken with the turkey mascot. Runners are invited to bring a food donation on race day for a chance to win prizes. Donations benefit Marana Food Bank.
