Almost 2 Million People Ran a U.S. Half Marathon Last Year—And Most of Them Were Women

Fitness trendsters, take note: it’s about time you go run 13.1 miles

Fitness trends come and go—remember Jazzercize?—and right now, the half marathon is ascendant. Last year, two million people finished the 13.1 mile race, and 61 percent of those runners were women. Those are huge numbers, and Scott Douglas and Dan Fuehrer at Runners World have more, charting the race's increasing popularity:

In 1990, there were an estimated 303,000 finishers. That total had more than doubled by 2004. This year's record total of 1.96 million means that, in just less than a quarter-century, there's been more than a six-fold increase in finishers.

The race seems especially popular in the United States, where 14 of the 20 most well-attended races were held. But the biggest races of all were overseas: 45,126 people finished a half marathon in Sweden last year, and 40,763 ran one in Great Britain. 

Running USA, the group that compiled the statistics for half marathon runners, points out a few other fun facts about just how many people are running these races:

  • Since 2010, 13.1 miles has been the second most popular distance by finishers behind the 5K.
  • Per our count, October hosted the most U.S. half-marathons (288), while January had the least (83) in 2013.
  • Since 2000, the number of half-marathon finishers in this country has quadrupled (482,000 to 1,960,000) or an impressive increase of 307%.

The difference between a half-marathon and 5K is huge: runners, it seems, are divided between people committed to running for maybe 40 minutes and people ready to hoof it for more than two hours. If you fall somewhere in between, well, maybe it’s about time you try for 13.1 miles. Everyone else is.
