Marathons have quickly become a popular pursuit. Hundreds of thousands of people submit ballots each year to run in some of the most prestigious races. In 2024, a record number of people crossed the finish line at some of the world’s biggest marathons. If you haven’t run a marathon yourself, chances are you know someone who has.
