After missing out on the top of the podium last year, Kenyan runners cruised to victory by comfortable margins at the Boston Marathon on Monday.
Geoffrey Kirui pulled away from American challenger Galen Rupp after Heartbreak Hill and Edna Kiplagat split from the women's field well before that, allowing both to cruise down Boylston Street with no need to look over their shoulders.
Their victories marked a sweet return to the top for Kenya after rival Ethiopia's 2016 sweep behind Lemi Berhanu Hayle and Atsede Baysa.
Kirui, who turned 24 in February, finished in 2:09:37 in just his third competitive marathon after debuting at Rotterdam and Amsterdam last year. He held off the more seasoned Rupp, who continues to grow his presence at 26.2 miles after stepping up to the distance for last year's Rio Olympics.
Rupp (2:09:58) was bidding to become just the second American man to win Boston in the last 34 years. The last was Meb Keflezighi in 2014; he raced in Boston for the final time Monday, weeks before his 42nd birthday, and finished 13th.
Kiplagat dominated the women's race, breaking away around mile 19 and running the last several miles completely alone before crossing the finish line in an unofficial time of 2:21:52.
Kiplagat, 38, won the world championships in 2011 and 2013 and has also won the New York, Los Angeles and London marathons, but had never run Boston before Monday. Rose Chelimo of Bahrain was second in 2:22:51 and 25-year-old American Jordan Hasay took the final podium spot in her marathon debut with a time of 2:23:00.
The elite runners were just a fraction of the more than 32,000 who set off Monday from Hopkinton and made the 26.2-mile journey to the finish line on Boylston Street. Warm conditions — the temperature topped 70 degrees before noon — tested the entire group.
Earlier Monday, there was a significant upset in the women's push-rim wheelchair race, where 17-time Paralympic medalist Tatyana McFadden saw her four-year winning streak come to an end. Manuela Schar cruised down Boylston Street alone in a course-record time of 1:28:17 for her first Boston win while McFadden ended up in fourth place.
In the men's push-rim race, Marcel Hug of Switzerland won for the third consecutive year while also setting a course record in 1:18:03. He edged Ernst Van Dyk of South Africa at the tape.
