She finished in 1,000,000th place.

Katherine Slingluff of Brooklyn crossed the 44th annual New York City Marathon finish line into the history books Sunday as the millionth person to complete the storied race.

The photographer and Alabama native scored guaranteed entry into the race for life and a shopping spree for marathon gear.

“That’s a nice treat, to be the millionth runner!” Slingluff, of Park Slope, told the Daily News. “I didn’t make my goal as far my pace goes, but I guess it worked to my advantage. That’s a nice cap to my run.”

The mother of two had hoped to finish in four hours, but she came in at 4:43:36. That’s more than two hours slower than Kenya’s Mary Keitany, who crossed the finish line in 2:25:07.

Slingluff said she opted to savor the race rather than push herself to maintain a 10-minute mile pace.

“I gave myself liberty to walk through water stations, I took pictures on the Queensboro Bridge,” she said.

Slingluff was among roughly 50,000-plus competitors who attempted the 26.2-mile route from Staten Island to Central Park.

Wilson Kipsang of Kenya won the men’s race with a thrilling show of dominance in the final stretch. He finished in 2:10:59.

The Kenyans’ triumphs came on a sunny, chilly day with winds hovering around 25 mph. Gusts were as high as 50 mph.

The blustery weather didn’t deter the thousands of spectators who, per tradition, brought food, drinks, signs and loads of encouragement for the runners.

Spectators lined Lafayette Ave. in Fort Greene for one of Brooklyn’s best marathon viewpoints between miles 8 and 9.

“The energy is incredible,” said Mark Wickens, a 33-year-old photographer who shot pictures for his portfolio.

Cops were everywhere along the route.

Carol Schoen, 56, and her husband Werner Schoen, 56, said they felt safe while cheering their 28-year-old son, Kevin.

“He could not sleep last night,” Schoen said of her son.

“He’s already a winner for us. If you run the marathon, you already won.”
