to be perfectly honest, I did not take part in it, although, I tried to get there but missed a deadline in, I think, 2001 - the time that for some reason I suffered from "Forrest Gump syndrome".
From you nick name, I guess that you do some martial arts. is that right?
how to train for it:
- whatever one says - it is STILL running event! Much tougher than an ordinary run, or even cross country run, but still run.
Therefore, you'll need to do "a bit" of it.
I'd say, you need to do 3 quality running sessions a week - 1 LDR - long distance run (also in wavy pattern, from 60-120 minutes - no need to do any longer), and 2 interval sessions including one "Fartlek", alternating it with hill work - I'd find a "tough ass" hill that will make you run for some 75-90 seconds and build it slowly from 4 to 10 x jogging/walking slowly down over the period of 6-8 weeks. than change for fartlek or other intervals, remembering to keep at least a few hills in your longer run (say on sunday).
Than, I'd say you need to do A LOT of ALL sorts of BODYWEIRGHT conditioning and bodyweight routines - one separate session dedicated to it, + some in your gym sessions and incorporated in the warm-ups sessions.
in addition couple of rather intensive but brief gym sessions using exclusively free weights: squats and variations, deads and variations, cleans, one are dumbbell cleans and snatches for high reps (these will make you F****ing tough) alternated with skipping rope or jogs... and other freakish methods to make you sweat.
Remember about chin-ups and pull-ups and all sorts of "crawly" movements (crocodile walk, spider walks, crabs, etc...) and various jumps and hops.
Well... too much to write just like this. . .
hope I covered all the major aspects of it
Try to put it all together, and... go for the bloody thing and make your mamma proud! get ready to get VERY dirty!
If need any help, let know!
