I run. I'm not the fastest person out there. I just get out there and do it. One foot in front of the other. And I am amazed, because I am probably the person you see on the street who is the one you think is the least likely to run a marathon (or a half anyway).
Then there are people who say to me, "I wish I could..." I always tell them "you CAN" and have coached a number of people online to begin to run. If I can do it, I really believe anyone can.
But this...this blows me away. If they can do it, we can all do it. Or do whatever it is we think we cannot do. We CAN do it!
