Anyone watch Letterman last night? Dean Karnazes was on, talking about ultramarathoning and his attempt to run 300 miles without sleep breaks. Nothing too deep about his training, but it was interesting. Dean seemed to get pretty good audience response- I think that they thought what he was trying to do was so far-out that it was almost funny. Letterman seemed to be a little at a loss of what to say to him. Overall a good exposure for distance running.
