what route are you doing? I did the century last year
The first twenty is'bt bad. Then you get on Mulholland Highway. It was very foggy. Lots o' climbing, with jaguar trying to make you into a hood ornament. Then you go down Decker. 18mph with the brakes locked. You join up the one of the metric routes. A couple of rollers, Then a big downhill into Camarillo - lots better, It's flat to rolling, until you get back to the Reagan library, there's a long hill past there, but's it not that steep. Then it's Fairly flat until you get back
