Argh! NoRacer, Josh, my sympathies to you both.
NoRacer, do you have any clues as to why your body is treating you like this? Any sports docs you can go to? I, too have had a few nasty cramps, but your account sounds like a horror story. Sheesh.
I've been mulling over the idea of a night century or metric century.
Might be a cooler way to get in a 100 miles.
