I am puzzled by the morphing of the title of this thread relating to ULTRA MARATHONERS to ULTRALIGHT MARATHONERS.

Personally, I have done medical work at many, many marathons, and I don't believe in those thousands upon thousands, I've ever seen a marathoner with a full pack.

I guess they are all unprepared. Of course, they compete in the Olympics, and we don't, so perhaps there is something to that.

Ultra Marathoners (100 miles, typically) is a different sport than hiking....so are simple marathons. I can't quite imagine what an Ultralight Marathoner would be----nude, I'd guess.

I'm not sure I'd be quick to criticize them for doing their sport that way it is usually done, because it is not done the way our sport is usually done.
