Kenyans shine in strong wins at Boston Marathon

Kirui outran Galen Rupp of the U.S.to take the men's race in an official time of 2 hours, 9 minutes, 37 seconds.

The Boston Marathon is the world's oldest annual marathon and one of the most prestigious races over the distance on the athletics calendar.

The first woman to officially run the Boston Marathon is back this year, 50 years later.

After the incident afforded her celebrity status, she joined Avon Inc.as an executive and helped create the Avon International Running Circuit of women-only races in 27 countries.

Ward, the Olympic marathoner from BYU and Davis High, placed 10th. Evans, who completed his 52nd marathon overall, said he wanted to show that Boston is back to normal. She'll run the race with a team of runners who will be representing her global running non-profit, 261 Fearless (named after her bib in the 1967 race). Shortly after the race began, one of the race officials, Jock Semple, approached Switzer.

Patrick Downes greeted the family of bombing victim Martin Richard after he crossed the finish line.

Spitzer said her return to the race in 2017 was a way to, "celebrate the fact, first of all, that I can run - that I'm capable of doing it, amazingly enough, and I'm very, very grateful for that".

The athletes had a tailwind of 13 miles per hour, the AP reports. That was the fastest marathon in history at the time, though not a world record because the Boston course does not qualify for world records. Switzer, who was attacked simply for wanting to run, became an worldwide feminist symbol and helped break the long-held barriers against women in long distance running. According to Running USA's 2016 State of the Sport report, females accounted for 9.7 million road race finishers nationwide previous year, and represented 57 percent of race event fields. They'll be followed at 10 a.m.by the elite men. She's joined in the field by countrywoman Buzunesh Deba, the 2014 champion. Linden took home silver in 2011 and made it clear that she was in Boston hoping to be first across the line and be the first USA woman to do so since 1985.

The 121st running of the Boston Marathon is getting underway in waves for the 30,000 athletes.

Wes Harding, Michael Master and Jennifer Gray got underway at 10:30am, while Ken Walker and Rod Fraser started their race at 10:50am.

The rest of the field will follow in waves.

The warm temperatures that hit 79 degrees at the 20-kilometer mark in Natick slowed the runners, but the strong tailwind was a boost - especially in the wheelchair races.

Security has been extra tight since 2013, when bombs killed three spectators and wounded more than 260 others.
