WASHINGTON, D.C. (WUSA) — Michigan native Desiree (Desi) Linden became the first American woman to win the Boston Marathon since 1985 on Monday, ending a long U.S. drought on a rain-soaked day.

The two-time Olympian and 2011 Boston runner-up, pulled away at the end of Heartbreak Hill to finish in 2 hours, 39 minutes, 54 seconds.

Supposedly, Linden’s end time could have been even better.

But get this, she slowed and waited for fellow American runner Shalane Flanagan to make a bathroom break.

Talk about sportsmanship!

At that point, Mamitu Daska of Ethiopia made a run for it and gapped the lead pack of women by 25 seconds.

Linden and Gladys Chesir of Kenya slowly pursued Daska down through the Newton hills, where Linden surged ahead after mile 20.

From there, Linden quickly created a 20-second lead over the final 5K. It was one of the slowest finishes in the last 40 or so years of Boston history, at the same time it was also contested in some of the worst weather conditions.

In Copley Square, crowds only partly thinned and muffled by the weather, greeted Linden with chants of "U-S-A!"

“I don’t have the right words,” she said afterward. “I’m thrilled . . . It's good to get it done.”
