For the fourth year in a row, Marcel Hug of Switzerland won the men's push rim wheelchair division, while American Tatyana McFadden won the women's push rim wheelchair division for the fifth time.
In 2011, Linden finished second in the women's division, just 2 seconds behind Caroline Kilel. She also was second at the US Olympic Marathon trials in 2012. Linden finished fourth in the Boston Marathon last year.
Earlier in the race, Linden temporarily took herself out of contention to help fellow American Shalane Flanagan. Flanagan dropped out of the lead pack to go to a portable toilet. Showing tremendous sportsmanship, Linden hung back to wait for Flanagan so they could both return to the lead pack together.
"Honestly, at mile 2, 3, 4 I didn't feel like I was even going to make it to the finish line," Linden said. "I told her in the race, I said, 'You know, if there's anything I can do to help you out, let me know because I might just drop out. When you work together, you never know what's going to happen. Helping her helped me and kind of got my legs back from there."
Flanagan finished sixth, one of six American women finishing in the top eight.
Before Linden, the last American woman to win the Boston Marathon was Lisa Rainsberger in 1985.
The last Japanese man to win the famous race was Toshihiko Seko in 1987. The last American man to win Boston was Meb Keflezighi, in 2014.
