Dress up as your favorite ghoul and run through Wentzville’s Historic Downtown!

The Halloween fun starts with the Monster Mash 5K Dash! The 5K course will be lined with not only your usual water stops but also candy stops for you to trick or treat along the way! As you run through downtown Wentzville you will have to watch out for the ghouls and zombies coming out of the shadows.

The fun doesn’t end when the race is over! Get your finisher’s medal, and head over to the Trunk-or-Treat at the Wentzville Fire Department to fill up on candy and treats from local business and organizations. For the over-21 crowd, you will receive a FREE drink coupon to enjoy a post race brew compliments of Friendship Brewing Company. Hang around for the Monster Mash BASH costume party at Friendship Brewing Company.

This race promises to become a Wentzville tradition! Be one of the first to run in this inaugural event.
