Broloppet was a running event that took place on the Øresund Bridge between 2000 and 2006. The event was organized by MAI and Sparta Atletik. The first event took place on June 12, 2000. With over entrants and finishers it remains one of the largest running events ever held, and the world's largest half marathon ahead of Göteborgsvarvet and the Great North Run .
The first race, which was won by Ethiopian runner Tesfaye Tola only three months before he won the bronze medal at the 2000 Summer Olympics, started at the Danish end of the bridge on the island of Amager, continued through the tunnel under the artificial island of Peberholm, over the Öresund Bridge to the finish in Limhamn in Malmö. The competition was originally meant to be a one-time event to celebrate the opening of the Öresund Bridge, but it continued on for six more years until it ended in 2006.
On June 12, 2010 the race was revived as part of the 10th anniversary of the Øresund Bridge. The race distance was the same as the original.
