Fitness Challenge

On one of the boards I follow, someone posted a fitness challenge. We were to each set goals for the remainder of the summer. I decided to challenge myself to do a 5k three times a week. I'm not particular on how I complete it (walk, run, eliptical) but I plan to run it at least once each week. I managed to get all three in last week and ran it yesterday so I'm off to a pretty good start. Once I've got the habit down, I'll add a challenge of having a more respectable time; yesterday's run came in just over 36 minutes (about 12 minute miles).
