100 Mile DAY?

My neighbor, Bill, left me a v-mail yesterday. He wants to know if I'm interested in a 100 mile ride (in a day!).

I'm REALLY, REALLY interested. It would be an amazing challenge. I think I can do it. The most I've ever ridden so far has been 42 miles.

I think if we can have the necessary time to do the 100 miles, I could get through it. We're looking at about 6.5 hours to get this done. This would be my "marathon."

I will never run a 26 mile marathon. My brain keeps entertaining the thought, but wisdom (and reality) have me thinking otherwise.

Riding 100 miles in a day though? That I know I can do. This Saturday though? I'm not sure. I can do 50 w/o a thought. 100? That's a LOT of miles.

What do you guys think?
