I know a few whom have done this. Chime in if you have done ironman or team on this. I am seriously considering doing this race next summer, prefer with a goup of guys (Briley, Jacob, Kyle???, others???) but would do this ironman as well. I know I would not be in it to win it but I do believe we could do a strong-ish finish.

I ran this 2 years ago. Was on a 66_ team... 6 man, 6 bikes. It was a fun coarse (took me an hour to finish one lap). We were very ill-prepared, and suffered for it. I don't recall how we finished... But that track was entirely different by the end of it.
I remember you telling about this, saying something like, "worst mistake I have ever done." That made we want to race it more! :) I am a glutton for punishment with riding in the dirt.
I probably said "most difficult"
I'm a slightly better rider today that I was in that race (still terribly fat and slow!), But it was not super technical.
