Pints Barn hosts a run every Thursday. There's lots of people (well over 100) and it's only 3 miles. Meet at the Pints Barn in Tumwater near Tumwater Falls. Stay afterwards for a cold brew or a hamburger while sitting out on their patio. See you there!
This event is with the Pints' Pavement Pounders Running Club: http://www.facebook.com/pintsrun
If you've never run with P3, come early because you'll need to sign a waiver.
