Next stop: Mohican 100

Just signed up for the Mohican 100 this weekend. Did the race 2 years ago, when the course ended up being in the 120+ miles instead of the promised 100. I also remember that I ran out of water at the end and I picked up a half full bottle of Gatorade that was laying along the route... uuuh, can't even think about it now how disgusting that was, but I felt like the luckiest guy that day!

I'm trying to figure out at the moment if I need the full suspension bike or if the hardtail can do the job?
