The Great GO! St. Louis Halloween Race features a half marathon, 10K, 5K and 1-mile fun run – with a special Halloween twist! From the serious road racer to the family dressed head-to-toe in costume completing the race together, this is a can’t-miss fall event!

Held in picturesque Eureka, MO and The Great GO! St. Louis Halloween Race will feature partnerships with local businesses, and of course – a top-quality race with all the great things you’ve come to expect from GO! St. Louis events!

In addition to our line-up of events, runners will be treated to great post-race amenities including plenty of candy (it IS Halloween, after all!), Schlafly beer for the over 21-participants, and a great festival area in Eureka’s business district!  And don’t forget to dress in costume – the Great GO! St. Louis Halloween Race Costume Contest will return this year!
