But one special day held recently involved a group of couples - and a sports day!
Taking place in Chengu, China, this unique ceremony skipped the traditional wedding reception of cutting the cake and the first dance for a day of activities.
After all 12 couples had exchanged their vows, the newlyweds and guests did everything from long jump to tug of war. It's certainly one way of bonding with your new spouse!
The wedding was organised by a building firm, where 12 of their workmen all got hitched at the same time.
And rather than a guestlist of their nearest and dearest, 1,000 of their colleagues attended the ceremony.
They even all got together to pose for a huge photograph on the racing track!
Li Hui, a 26-year-old migrant worker, said: "I still couldn't believe my wedding would be blessed by so many people."
