Do you ever wonder if you would be able to run a marathon? I think the answer is: yes. The only question is: in what time? A few years ago I wrote about a man who took about six hours to walk 26.25 miles (42.195 kilometers). He felt like the king on the track, enjoyed the cheers, raised his arms in the air with every fifth step. Who knows, if he had saved himself that, he could have gotten a few more minutes out of it.
