Join us at Tower Grove Park on Earth Day for an evening 5K that gives back to our community and planet. At this unique type of 5K, we’ll be incorporating eco-friendly measures and partnering with local organizations to help create a more sustainable future.

In an effort to support a local charity that benefits the earth, a minimum of $5 of your registration fee will be donated to Forest ReLeaf of Missouri, whose mission is to enrich communities by growing and planting trees through the power of people and partnerships.

The 8th annual Bootlegger 10K trail run will be held on Sunday, February 22nd, on upper Creve Coeur Park's Bootlegger's Run trail, which gets its name from the area's notorious reputation during Prohibition. According to one account, "Prohibition brought gamblers and gangsters back and clubhouses, roadhouses, and the notorious Creve Coeur Hotel provided havens for crime.” Another history offers, "Around the 1920's the area began to decline in popularity as gangsters and hoodlums began to frequent the saloons, restaurants, and nightclubs located at the lakefront. By the end of Prohibition, Creve Coeur was almost exclusively a gangster hideout." Today, Creve Coeur Park has regained its pre-Prohibition notoriety as a beautiful locale for enjoying nature. It is regularly filled with St. Louisans running or biking the trails, riding zip lines at Go Ape, sailing or rowing on the lake, or simply having a picnic.

The beautiful Bootlegger 10K course is primarily single-track trail and includes plenty of turns, switchbacks, and hills. Look closely and you may see remnants of the Creve Coeur Lake streetcar line that brought ne'er-do-wells to the area during Prohibition. Add winter weather to that mix and the Bootlegger 10K will surely test your will against Mother Nature at her toughest.

All registrants receive a custom finisher item (details coming soon), and the option to purchase a commemorative long sleeve tri-blend shirt. Finishers can enjoy snacks and post-race beer.
