Back in 05 I completed 23 centuries. Plenty of flat and some good climbs. I don't see much difference between a flat 100 and a double metric with rolling hills and a couple of big climbs like CoolBreeze. A few riders described the big Casitas Pass climb. Once I was over it, I was still loooking for a big climb!

Nothing different IMO between the two! If you want a mental difference, do a ride like this one, "Ride Around the Bear". This changes one's mindset a bit.

I did it 3 years in a row and plan 05,04, and 03. This year I plan to do it again in June with RonSmithJr!

ANd like yuo, my typing was much bettre before I started riding centrees!
