Ran/walked for 60 minutes

I drove to the East Pavilion in South Jordan and ran for 30 minutes going south and then returned for a total of 60 minutes and 2.82 miles. It was a nice day with temperatures in the mid 60s (F). My right quad has felt fine for the past couple of weeks. My right leg, though, is swollen, compared to the left leg. The swelling seems to be going down.
