Talk about setting a personal record.
The 2016 Airbnb Brooklyn Half sold out online in 52 minutes Thursday afternoon, crushing its time of 6 hours and 46 minutes from last year, New York Road Runner spokesperson Lauren Doll told us.
If you won't be one of the 27,000 runners to participate in this year's race, we've rounded up a number of alternatives you can still sign up for:
► Prospect Park Track Club Cherry Tree 10 Miler
Starting line: The Lincoln Road entrance to Prospect Park, along Ocean Avenue, Prospect-Lefferts Garden
Date and starting time: Feb. 14, 10 a.m.
This Valentine's Day 10-miler rings around Prospect Park three times. The race won't take you to Coney Island, but there will be hot chocolate at the finish line. Registration costs $35 if you sign up by Feb. 9. It costs $50 on race day.
► NYCRUNS Frozen Penguin Half Marathon
Starting line: Shore Road and 69th St., Bay Ridge
Date and starting time: March 12, 9 a.m.
If you're set on running 13.1 miles and you're in decent shape already, this could be the race for you. You'll have a nice view of the Verrazano Bridge and the Manhattan skyline as you hoof it along the Shore Parkway Greenway trail. Entry costs $40 through Feb. 2 then $50 until online registration closes. If you want to sign up race day and slots are still open, it will cost you $60.
► NYCRUNS Ladies First Half Marathon
Starting line: Shore Road and 69th St., Bay Ridge
Date and starting time: April 2, 8 a.m.
Gentlemen, you're welcome to run this half marathon, too, but you won't qualify for any awards. Entry costs $40 through March 28.
► Rock ‘n’ Roll Brooklyn Half Marathon
Starting line: Grand Army Plaza, Prospect Heights
Date and starting time: Oct. 8, 7 a.m.
The exact course for this year's Rock 'n' Roll half marathon has yet to be set, but it will end in Prospect Park. The best perks of this race, which debuted last year: you'll hear local bands playing and cheer squads rooting for you while you pound the pavement. And you'll get a frosty beer at the finish line.
Registration has yet to open.
► Brooklyn Greenway Half Marathon
Starting line: TBA
Date and starting time: Oct. 16, 9 a.m.
This half marathon, following a path along the East River waterfront, "offers unique and memorable urban views including the skylines of Midtown and Lower Manhattan and the iconic Brooklyn, Manhattan and Williamsburg Bridges." Expect bagels at the finish line.
This race is a little pricier: you'll pay $50 to register through May 30, $60 through Sept. 30, and then $70 until the closing of online registration. On race day, you'll pay $80.
Some of the money will go to support the Brooklyn Greenway Initiative, a nonprofit charged with the creation of the Brooklyn Waterfront Greenway, a 14-mile route for pedestrians and cyclists between Bay Ridge and Greenpoint.
Starting line: The middle of Prospect Park
Date and starting time: Nov. 20, 8:30 a.m.
Why not go all the way and sign up for this 26.2-mile race? Named "Marathon Of The Year" in 2012 by Runner's World, the Brooklyn Marathon will be in its sixth year and it attracts runners from all over the world.
Entry costs $95. The race is capped at a mere 500 runners, so sign up as early as you can.
