The 2025 Bridge Run takes place this weekend, commemorating the 25th anniversary of the opening of the Öresund Bridge between Copenhagen and Malmö.

The event sold out faster than a Usain Bolt sprint and 40,000 runners are now scheduled to take part in the unique half marathon on Sunday June 15th.

While the race itself begins at 10am, traffic is expected to be disrupted throughout the morning and afternoon.

Vehicles will still be able to cross the bridge throughout the day, but reduced speeds and delayed journey times can be expected between 6am and 5pm.

“You should certainly expect extended travel time over the Öresund Bridge on June 15th,” John Alexander Sahlin, press adviser with bridge operator Øresundsbron, told news wire Ritzau.

Traffic will be one-way through the tunnel between 9:30am and 1:30pm, with the direction changing roughly every 15 minutes.

A single lane only will be open in both directions between 6am and 9:30am, and between 1:30pm and 5pm.

Rail traffic will also be affected by the road closures on the bridge. Øresundsbron advises travelling before or after the event where possible.

“If, for instance, you have planned a little trip to Sweden that day, we recommend finding another day,” Sahlin said.

Some traffic disruption can also be expected around the starting area of the event in Tårnby south of Copenhagen, and the finishing area at Sibbarp in Malmö. Train stations at Copenhagen Airport and Malmö Hyllie could also see congestion.

Participants in the race can use special buses provided by the Bridge Run organisers to travel between the two cities. Race bibs must be shown when you board.

Because of the nature of the event – it’s mostly on a bridge – the options for spectators are more limited than you might usually find at marathons and other popular running events.

But there are places you can go to cheer on your loved ones and other runners, in both Copenhagen and Malmö.

On the Danish side, the first two kilometres of the course will be open to spectators. This covers the stretch from the start line at Øresundsparken near Amager Strandpark, with music and entertainment at a “power point” in the town of Kastrup around the 1-kilometre mark.

In Sweden, you’ll be able to access around one kilometre of the final stretch leading up to the finish line in Sibbarp. This comes after the runners leave the bridge and the motorway toll area and are running along more regular streets. You will also be able to find entertainment zones in this area and around the finish.

Maps showing the areas accessible for spectators can be found on the Bridge Run website.
