Cali:
I agree not really any scary hills at least for me. But some of the TE gals are new riders and there are hills (like through Summerland) which are steep and winding and of course, there is the descent off the back side of the Century. A hell of a fun ride down but can be intimidating for a newbie. For me the only reason to climb is to take the downhills!!!
Cali - how long will it take you to do the double metric? Last time I did the Century it took me (including stops and lunch) 8 hours. I'm fast on the flats but very slow on all those hills.
