Free shoes in New York. PUMA is bringing its NITRO Lab to the city for marathon weekend, and anyone who runs 1K in under four minutes wins a pair of the Fast-R NITRO Elite 3. I was at the NITRO Lab in Los Angeles during the World Cup this summer, and it was a wild experience .

Where to Get It

The NYC NITRO Lab sets up at Seaport Square on Pier 16 on Friday, October 30, and Saturday, October 31, from 10 a.m. to 5 p.m. On race day, Sunday, November 1, the Lab goes mobile at spots across the city, so runners can take the challenge right after they finish.

Run 1K in under four minutes, and the $300 shoe is yours. If you've been running and you're ready, this is a great opportunity.
