Interesting Ultra Stats

Below is a post from Pete White posted to an Ultra Running group that I subscribe.  He compiled a list of ultra running stats from 2010 including 64 races.  While his stats may not be scientific, it does offer an interesting glimpse into the ultra running world. 

According to the Run100s website  in 2011 there are 90 hundred milers in North America so approximately 80 in the US if their list includes everything and is up to date.  

The information below is being shared with his permission.

Hi all,

I recently had a fabulous time completing my first 100 miler
(Philadelphia 100). In writing up my race report
(http://on.fb.me/ia1p71), I thought it might be nice to include how many
people in the US typically complete a 100 miler in a year. It took a
while to figure this out, and in so doing, I was able to compile some
interesting stats about the 2010 season. So here they are, enjoy!
