The Haunted Halloween Half Marathon & 5km returns this fall to Chicago's Lincoln Park, at a new site! We will be in Diversey Event Space, across the street from Notebaert Nature Museum. The event offers race distances of half marathon and 5K ― with a special Halloween twist! Hundreds of runners and walkers of all ages and abilities dress in costume and compete for fun and prizes. Age group awards will be given in ten-year age ranges. And there is prize money for the winners of our pre-race Costume Contest! Costume Contest Prize Money: For the teams 1st, 2nd win $200 and for individuals 1st, 2nd win $100.

After the race, help yourself to some autumn refreshment treats. There will of course be Halloween candy. Every HM & 5k finisher gets a H^3 medal to match your bib and shirt! Please attend our post party with a free beer at Tin Lizzie in Lincoln Park where they will also be offering 20% discount on their food menu.

About Chicago

Learn more about the host city, Chicago.

Chicago is the home of the blues and the truth of jazz, the heart of comedy and the idea of the skyscraper. Here, the age of railroads found its center, and airplanes followed suit. "Stormy, Husky, Brawling / City of Big Shoulders," Chicago is a Heartland boomtown, its ethos defined by urban planner Daniel Burnham's immortal vision: "Make no little plans; they have no magic to stir men's blood." It is one of the world's great cities and the third largest city in the United States, behind only New York City and Los Angeles.
