Onlookers in the Big Apple witnessed history in the New York City Marathon on Sunday.

Mary Keitany made it three titles in a row after placing first in the women's competition, while Ghirmay Ghebreslassie, 20, became the youngest runner to win the men's title.

Below are the top 10 finishers from each of the two divisions:

ESPN's Darren Rovell provided Keitany's and Ghebreslassie's average mile times:

Keitany prevailed in dominant fashion, finishing a little less than four minutes ahead of runner-up Sally Kipyego.

William Ruto, the deputy president of Kenya, was at the finish line to cheer on Keitany:

Her competitors might have hoped the 34-year-old would begin wearing down midway through Sunday's race. Instead, Keitany continued to run a blistering pace even deep into the event. RW Advanced noted how quickly Keitany completed her mile splits:

"I am very excited to win three times," Keitany said, per the New York City Marathon's official Twitter account. "It's not easy, but I got it. It means a lot to me."

According to the Associated Press' Larry Fleisher (via ABC News), Keitany is the first female runner to win the event in three consecutive years since Grete Waltz won five years in a row between 1982 and 1986.

Ghebreslassie won in similarly convincing fashion. Lucas Rotich crossed the finish line a little over a minute after Ghebreslassie, and Science of Sport's Ross Tucker tweeted the young Eritrean had the victory all but sewn up in the race's final stretch:

The race's official Twitter account shared a clip of Ghebreslassie running through Central Park as he traversed the back half of the course:

The fortunes of Lelisa Desisa changed rapidly late in the race.

The 26-year-old Ethiopian is a two-time Boston Marathon champion and finished second in the marathon at the 2013 World Championships. Desisa was one of the top contenders coming into the New York City Marathon and lived up to the hype for most of the event.

With about five miles remaining, though, Desisa began showing major signs of fatigue and started falling off the pace. By the 22nd mile, he left the race altogether, according to the Chicago Tribune.

Desisa's exit left Rotich as the only realistic challenger to Ghebreslassie, allowing the eventual winner an easier road to the finish line.

Based on his New York City Marathon triumph, Ghebreslassie appears to have a bright future ahead, and Sunday won't be the last time racing fans see him earn top honors at a marquee event.
