Did you know that the Boston Marathon was once called the American Marathon? And that it wasn’t until 1972 that the marathon finally had official female entrants? With the annual marathon event so deeply ingrained in our city’s culture, it’s hard to believe that it was ever any different.

But as you can see from this Runner’s World infographic, created by Dan Fuehrer and Scott Douglas, a lot has changed since 1897.

The two compiled interesting tidbits about the Boston Marathon, including little-known history facts and important stats. Senior content editor of Runner’s World, Scott Douglas, tells BostInno that the most surprising thing he discovered had to do with the first historical item: the marathon’s name.

“When it was started, the race was known as the American Marathon,” Douglas explains. “One of my colleagues asked, ‘When did the name change to the Boston Marathon?’ When I started trying to determine that, I found the simple question wasn’t so simple,” he continues. “As it turns out, the answer is: Nobody knows.”

He also points out to BostInno the steady rise in percentage of women finishers. Douglas hopes the marathon will soon make history by reaching “at least 50 percent” of women finishers.

Regardless, it looks as though this year’s Boston Marathon is set to make quite a few waves of its own. After last year’s horrific bombings, many feared participation would be down in 2014. Fortunately, the city of Boston and 36,000 runners worldwide proved this to be wrong. The 118th Boston Marathon will have more runners than “any year before,” except for the 100th anniversary in 1996 which had 38,000, according to the Huffington Post.
