An annual Seven Mile Bridge run takes place every April in the Florida Keys. The distance of the race is a bit shorter than seven miles—6.8 miles or 10.9 km to be exact. The race starts after the bridge gets closed for traffic at 7:30 am. Runners will have 1.5 hours to complete the run. If they can't do it in the designated time, they will be picked up by a bus. There is a 1,500 people limit for this race, and slots are determined every year by an online lottery. This scenic race is very popular so it's rather hard to get in.
The Seven Mile Bridge Run was first held in 1982 to mark the completion of the bridge, which was reconstructed after being damaged by two hurricanes in 1935 and 1960. The iconic 7 Mile Bridge was one of the longest bridges in the world during the times of its construction, connecting Knight's Key (the town of Marathon, Florida) and Little Duck Key. It's a part of the Overseas Highway in the Keys. There is also an older bridge known as the Knights Key-Pigeon Key-Moser Channel-Pacet Channel Bridge, built in 1912, that is now open just for pedestrians and cyclists.
