Youtube is a wonderful medium. If I feel that I need some motivation to get out and do a long run, despite grotty weather, or too hot or whatever excuse comes to mind. I find a good way to inspire me to get off the couch is to start surfing some of the youtube videos. Here is one I recently stumbled across. It features Ultramarathoner/Navy Seal David Coggins on a 15o mile Ultra.
As I find more, I'll post them - plus I will post some of my favorites.
