I'm doing the Sea Gull Century tomorrow and I've not prepared for this in the slightest. I've known about if for months and I ain't done sheeyit. I expect the suffering/fun ration to be quite high. Having said that there is one crucial step in my lack of preparation that I didn't overlook. The Bike.
Here's how I get my Bianchi EV3 Reparto Corse ready for a ass chaffing century. I slap on my big couch of a Brooks B-17.
Ah ain't skeerd.
(I'm a little scared)
