I just completed a training trail run with RunKeeper http://runkeeper.com/activity?userId=30039243&trip=471826551
I did 45 minute at the gym working on my arms.
I have now done several run in my new Reebok shoes and really like them. They are nice and light and breathe well and keep the dirt and rocks out. Haven't had a chance to test them with mud, but that most like will be with the next obstacle course race I do.
