Walsh Takes a Hike

Now we know how she gets that bikini body!

Kate Walsh got her fitness on at Runyon Canyon in Hollywood today with a friend and her dog.  The Private Practice actress wore a loose fitting t-shirt and a pair of leggings for the strenuous workout, but was still able to manage a smile when she encountered the paparazzi along the way.

Always a class act, this one!
