Ultra-Marathon Training

No experience, but I recalled an old thread that might point you in the right direction:  http://www.beginnertriathlete.com/discussion/forums/thread-view.asp?tid=16582&posts=10&highlight=ultra%20training&highlightmode=1#M148980

There were some more threads that might have had additional stuff too.  Might want to do a search to check them out.

lot's of resources/links here:

To start, I have not yet done an ultra, but have plans on doing one either later this year, or next (probably a 50k, there's one in SEP.).

From what I have read and learned from discussion, most of the ultra peeps are of three basic camps: A) train like a regular marathon; B) train like a marathon, but increase the long run distances some; C) just always run as much as possible.  If you're not currently running 50 mpw+, then I would probably work on building up to that and holding it for a good 8 weeks.

For most of the ultras, speed work isn't overly important.  It really comes down to aerobic endurance, and efficiency.  If you're talking a trail ultra, then the big thing you need to work on is downhill running.  From personal experience on trails, and from conversation, dead quads are a big deal come the end of a race.

When it comes down to it, I have only really looked at one ultra training plan (Higdon has one for Comrades).  I might borrow from it, but I won't necessarily follow it specifically.  To me, a big thing would be water.  I'd start looking into a CamelBak or something along those lines.  There's a number of options out there.

Hope that helps. 

I will be doing my first ultra this year and i'll be using Hal Higdon training program.
