Haunted Halloween - Chicago

Haunted Halloween - Chicago is based at the Diversey Event Space in Lincoln Park, Chicago, Illinois, on October 25, 2026. The half marathon (13.1 miles) starts at 8:25 a.m. and the 5K at 8:40 a.m., with the route going through Lincoln Park and along the Lakefront Trail. Costumes are common and the best ones win prizes, cash included; every finisher takes a medal, and there are age-group awards, refreshments and an after-party.

A half marathon through a city park and along a lakefront path is a fair setting for a first attempt at the distance or for a genuine time trial. Run the opening three miles slower than feels right and the last three will look after themselves. A 12-week build with a long run reaching 11 or 12 miles is the standard preparation; the 5K is the alternative if you want the same morning without that commitment.
