Many ultra-marathoners will run at a 9.5-minute mile or slower

Um, that pace will win you the race, LOL!

This makes no sense. 

He pushed through the searing lactic acid buildup, pumped his heart to the max, and reached the point where he started calling on carbohydrates rather than fats for energy. Once he reaches that "crossover point" and the carbs are depleted, his body forced him to call it quits.

[merigayle]

his weakness made him call it quits, not his body :p

If his metabolism actually worked that way (burning fats before carbs), he would be a medical miracle.  Ultra-alien

You can't run a sub 16 hour 100?!

I thought they were referring to aerobic threshold.

Yeah, who knows.  It sounded to me as if she was saying the guy on the treadmill ran until he had to switch from fat metabolism to carb metabolism.  Which is correct I suppose if you are talking about running at an all-out level of effort.  But nobody runs an ultra with the pedal to the metal.  Wasn't the article supposed to be about ultra running?  For anything at the marathon distance or better, it kind of works the other way.  You deplete the body's store of CHO first, and then you have to switch over to fat metabolism to keep going.

It's some pretty shitty writing.  No, wait, the whole thing is bad.

I've only ever run 31 miles at the most, so I've never hit the wall.  Don't know what it feels like.

The mystery continues.  He hit the wall in 45 minutes, and speaks of many walls-

Lol, and how about that special sports drink that brought him right back from the brink of  metabolic depletion...  Water!

45 minutes?  maybe it was a jersey barrier.

i hit the wall at mile 20 of a gnarly 50.  but i found my second (third, fourth, and ninth) wind the minute i saw a big, fresh, kitty print in the dirt.

[Fionn mac Cumhail]

I've never hit the wall in a 30 mile training run or in the one 50 I've run, but I can hit the wall a few times around 22 of a marathon...but, I run marathons WAAAAAY differently...I give a shit about time in those...

Actually, I run a sub-14 100.  Just sayin'.
