I took a 90-minute lunch hour to complete a 5-mile walk to and from the Boston Naval Shipyard where the USS Constitution can be found.  Had time permitted, I would have liked to also take the 30 minute tour but my work calendar dictated otherwise.  Perhaps I will do this again when things are less busy (we have a big product launch coming up). I am signed up for a 10-mile Tough Mudder in June and my spring soccer season is just a few weeks away so I am trying to increase my fitness level.  I should be running, but long walks are far less aggravating to my patellar tendonitis.
