There's an equipment list on the site. Personally I would recommend one of those snow cats that climb Mount Washington. Not to deter anyone or anything, but realize it could be like -30 the day you ride.
i was reading some guys blog that i stumbled upon the number of 24 hour events. Excluding Sean bc hes not human. They sound like just hell. however since we all enjoy tourturing ourselves, i just may do some someday.
Which leads me to my next question. What would a good event be for my first race or big ride? I know of the 24 hours of allamuchy and that h2h series. Would that be a good place to start?
considering the terrain you're currently used to, i would recommend allaire as perhaps your first race. i know they hold a few there nearly every year(right?). you could certainly go anywhere and race and i think you would do well and have a good time, but you might find that place more enjoyable in a race than one of the rockier courses with longer climbs. however, if you go ride sourlands and chimneyrock a bunch, it would certainly have you better prepared for a race anywhere. i don't know that the 2007 schedules are out yet.
my first 24 hour race was with a 'team', and i think that's perhaps the best intro to the discipline.
