Mount Washington Hill Climb

I signed up for the Mount Washington Hill Climb this summer in New Hampshire and would like some input. I know its been done a few times before so I’m looking to gleen from your experiences:

-Is anyone else signed up on a uni?
-What wheel and crank size would work? I’ve done hill climbs on 24" with 125s and my Coker with 175s
-Is the dirt section an issue? Wind? Cold?
-What is the record for the climb?:
-Was this a really dumb idea?

Thanks for any imput

Ben Plotkin-Swing, Mike Tierney and Joe Merrill did it a few years ago:
