The fourth annual National Running Day in the U.S. will take place on Wednesday, June 6, 2012. The purpose of the day is for “runners everywhere share their passion for a lifestyle that is one of the best, and simplest, ways to stay fit”. 
All it takes to participate in National Running Day is to get out and run, whether it’s with a group or alone. There’s no minimum distance required — you can also run/walk if you choose. If you’ve long forgotten about your New Year’s resolutions, National Running Day is the perfect time to start fresh with some new fitness goals. To hook up with a group in your area, search the database for events or organize your own run.
Whether you’re a beginner or seasoned runner, National Running Day is the perfect excuse to run and celebrate all the reasons to love running.
