12th Asta Maries 6 Timers Løb Night 2026

Asta Maries 6 Timers Løb Night is an ultra running event held in Copenhagen, starting at Sortedamssøen near Østerbrogade 19. Participants can select from 6, 12, or 24-hour races, or a 100 km option, all commencing in the morning. The course is a DAF-measured loop of 1,910.25 meters, emphasizing consistent laps over point-to-point travel. It holds an IAU Bronze Label, and includes solo entries as well as two-person and four-person teams for the timed events. The route follows Sortedamssøen clockwise, a flat path comprising gravel and road surfaces. Those in the 12-hour and 24-hour races will switch direction every six hours. While the course is marked, it remains accessible to the public, meaning runners will encounter regular city activity. The aid station provides practical provisions: cola, chips, energy products, water, fruit, hot blueberry soup, and hot food served in the evening. Participants are required to bring their own cup for beverages, a small plate, and a spoon for the hot meal. The event contributes 50 DKK per participant to TUBA.
