Halvmaraton is a 21.1 km road race in Aarhus C, Denmark, starting and finishing on Carl Blochs Gade, near the park and Folkestedet. Aarhus 1900 Atletik og Løb organizes the event. Participants are assigned to start groups based on their registered finish times, with pacers available for target times from 1:30 to 2:10. The race has a three-hour limit, four aid stations providing water and energy drink, and complimentary baggage storage at the event area.
The course departs Carl Blochs Gade, passes under Ringgadebroen, circles Brabrand Lake, and returns to Carl Blochs Gade for the finish. The final section often sees crowds lining the street, creating a city-street atmosphere rather than a quiet park run. The entry package includes fruit, a towel, a soda, and a choice of medal. The event area offers food, beer from Ebeltoft Gårdbryggeri, a prize draw for all participants, and specific prizes for the fastest male and female runners.
