Get ready to embrace the spooky spirit at the I Ain't Scared (of 5k) in Thornton. This unique event invites runners to dress up in their silliest or scariest costumes for a festive race experience. Enjoy fun music and a variety of Halloween-themed snacks as you celebrate the season. The race features a special glow-in-the-dark T-shirt and a finisher medal for every participant. Because this event only occurs when Halloween falls on a weekend, it is a rare opportunity you won't want to miss.
