50,530 runners triumphantly crossed the finish line at the NYC marathon yesterday. Weather conditions were ideal yesterday, with overcast skies keeping things cool for the masses as they pounded the pavement through five boroughs from Staten Island to Central Park. The winner in the men's group was Stanley Biwott, from Kenya, who finished in 2 hours, 10 minutes, and 34 seconds. Mary Keitany, also from Kenya, won the women's division in 2 hours, 24 minutes and 25 seconds. They each hobbled away with $100,000 in prize money.

But the 50,528 losers still seemed to enjoy the experience, with many donning creative costumes that seemed antithetical to the activity at hand. During just a few minutes spent watching the runners sprint by on Bedford Avenue in Williamsburg, I spotted a marathoner in a tuxedo; another running the race inside a hand-made Japanese drink box replica with holes for arms, legs, and head; and a firefighter who appeared to carrying an oxygen tank. It was exhausting just watching them, and after five minutes I had to take a nap.

Celebrity participants included Alicia Keys and Ethan Hawke (both ran for charity), as well as ex-tennis pro James Blake, Sean Combs, Ed Norton, Katie Holmes, and Pamela Anderson. The marathon's grand marshal this year was filmmaker Spike Lee; he posed with Keys for a photo before the race started.

Click through for Scott Lynch's photos from race day. Lynch stopped by multiple spots along the route in Brooklyn, and notes, "Over the years the NYC Marathon has evolved from pure sporting event—though the race is one of the most prestigious on the professional marathon circuit—into more of an individual endurance and empowerment test, combined with massive block party.

"Along the Bedford-Stuyvesant and Williamsburg legs of the course yesterday (miles nine through eleven, approximately) the day was as much about doughnuts, beer, making noise, family time, musical entertainment, and witty signs as it was about athletics. Unless you were out there running, of course, then it was probably about personal bests and holy crap I'm thirsty and survival."
