Desiree Linden splashed her way through icy rain and a near-gale headwind to a Boston Marathon victory on Monday, the first American woman to win the race since 1985.

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. That was more than four minutes better than second-place finisher Sarah Sellers, one of seven Americans in the top 10, but the slowest time for a women's winner since 1978.

"It's supposed to be hard," said Linden, who wiped the spray of rain from her eyes as she made her way down Boylston Street alone. "It's good to get it done."

Yuki Kawauchi passed defending champion Geoffrey Kirui in Kenmore Square to win the men's race in an unofficial 2:15:58 and earn Japan's first Boston Marathon title since 1987. Kirui slowed and stumbled across the Copley Square finish line 2:25 later, followed by Shadrack Biwott and three other U.S. men.

On the fifth anniversary of the finish line explosions that killed three and wounded hundreds more, Linden and Kawauchi led a field of 30,000 runners through a drenching rain, temperatures in the mid-30s and gusts of up to 32 mph on the 26.2-mile trek from Hopkinton.

"For me, it's the best conditions possible," Kawauchi said through an interpreter and with a wide smile.

In Copley Square, crowds thinned and muffled by the weather greeted Linden, the California native who lives in Michigan, with chants of "U-S-A!"

Lisa Larsen Weidenbach's 1985 victory was the last for an American woman — before the race began offering prize money that lured the top international competitors to the world's oldest and most prestigious annual marathon. Linden nearly ended the drought in 2011 when she was outkicked down Boylston Street and finished second by 2 seconds.

Marcel Hug of Switzerland earned his fifth wheelchair victory, and American Tatyana McFadden won the women's wheelchair race for the fifth time, pushing though puddles that sent the spray from their wheels into their eyes.

"It was just tough, it was so freezing," Hug said through chattering teeth as a volunteer draped a second towel around his shoulders. "I'm just very glad that I made it."

Japan's Yuki Kawauchi surges to win men's Boston Marathon

Japan's Yuki Kawauchi (YOO-kee KA-wa-oo-chee) surged with a mile to go to overtake Geoffrey Kirui to win the Boston Marathon on Monday.

Kawauchi crossed the finish line in a time of 2:15:58. He becomes the first Japanese man to win Boston since Seko Toshihiko took the title in 1987.

Kawauchi said through an interpreter that the wind and cold were the "best conditions possible" for the race.

Kenya's Geoffrey Kirui was second in 2:18:23, followed by American Shadrack Biwott in 2:18:35. Biwott's result marked a huge day for the American men which placed three runners in the top 5. It marks the second straight year that six American runners placed in the top 10. Tyler Pennel was fourth (2:18:57) and Andrew Bumbalough finished fifth (2:19:52).

Meanwhile, the usually strong Kenyan team had only one runner — Kirui — in the top 10.

It is the first major title for Kawauchi.

Kawauchi sprinted out to an early lead before falling back. Fighting rainy conditions and a heavy headwind, he surged several times during the race.

Though he had never won a major marathon crown, the 31-year-old had captured more than 30 marathon titles in career. He ran 12 marathons in 2017 alone, winning five.

In majors, he finished fourth in Tokyo in 2010 and third in 2011 in the same race.
