Copenhagen's Asta Marie 24-Hour Ultra Race returns for its twelfth year, offering runners an unforgettable challenge and experience. Set against the vibrant backdrop of either Sortedam Lake or Amager Strandpark (depending on final venue announcements), this event caters to both seasoned ultrarunners and those seeking a taste of longer distances. The race features several formats: - A 6-hour run for newcomers looking to dip their toes into ultra-distance running. - The 12-hour challenge, which demands endurance and strategic pacing over an extended period. - The ultimate test: the 24-hour solo or relay event where runners aim to cover as much ground as possible within a day. - A classic ultradistance option in the form of a 100 km race. Participants can also choose from night races for 6 and 12 hours, providing an opportunity to experience running under starlit skies. The event offers relay options for both 12-hour and 24-hour distances, allowing teams to share the challenge. The route circles around Amager Strandpark or Sortedam Lake in a clockwise direction, with changes every six hours during longer events like the 12- and 24-hour races. Each lap measures approximately two kilometers, making it easy for runners to track their progress while enjoying scenic urban landscapes. Runners will find themselves immersed in a lively atmosphere supported by enthusiastic spectators throughout the day and night. The aid station at the start/finish line is well-stocked with refreshments such as soft drinks, chips, sweets, water, and fruit, ensuring participants stay fueled for every lap. Entry fees vary based on race format: - 24-hour solo: DKK 500 + online fee - 12-hour solo: DKK 450 + online fee - 6-hour solo: DKK 400 + online fee Relay teams and marathon options also have their own pricing structures.
