Copenhagen Marathon 2026 is sold out in just 23 hours

New record: 23,000 Marathon entries sold in just 23 hours. According to the organizers, the success is largely due to the city of Copenhagen and its residents.

Two years ago, Copenhagen Marathon sold out for the first time ever – after about six months. Last year, it took 12 weeks.

This year, 13,000 people were in the waiting queue when registration opened at 11:00 AM on Tuesday, and – just 23 hours later – all entries are completely gone.

“After this year’s successful event, we were prepared for high interest in Copenhagen Marathon, but we’re still surprised at how fast it sold out,” says Lars Nissen, Head of Events at Sparta Athletics & Running. He offers his take on the overwhelming demand:

High evaluation score from the runners

The impressive registration rush follows a successful race just two and a half weeks ago, where participants gave record-high scores in post-race evaluations.

Around 7,000 runners from this year’s marathon completed the post-race survey, rating their overall experience an impressive 9 out of 10. The Net Promoter Score (NPS) is also high – 78 among Danish runners and 82 among international participants.

Next year’s edition of the Copenhagen Marathon will take place on Sunday, May 10.

Number of Registered Runners (approx.):

  • 2026: 23,000
