What could you do with 10 minutes?

It’s enough time to tackle a couple quick household chores: swap the laundry, wash a few dishes. You could make toast, scroll through the day’s headlines, or take in a few cat videos.

But could you walk to a park?

To the people who have them, parks provide countless benefits. From picnics, ballgames, and playgrounds to running, cycling, or just sitting quietly on a bench in the shade, parks are where people go to relax, recreate, play, and connect to nature—and each other.

But today, 1 in 3 Americans don’t have a park within a 10-minute walk of home. If you live in one of the many cities where great parks are too few and far between, you know just how hard it can be to find a place to get outside.

Today, we’re proud to launch a nationwide campaign to ensure that everyone, in every neighborhood, in every city across America, has a park within a 10-minute walk of home. We’re challenging mayors to com­mit to making the 10-minute walk to a park the standard for all resi­dents in their city. From coast to coast, mayors in more than 120 cities, large and small, have already signed on—and this is only the beginning.
