Colorado - most of the year! I only started last year. I do not do the competitive (yet- in my dreams) - heard there is some good things going on. The Rockies protect us down in the Springs 70mls S Denver and those foothills are closer for some good rides, 300 sunny days a year in our state. Some cold, snowy days; but, it never hangs around for long. You have flat, rolling hills, bloody great hills and some even bigger than that! Mount Evans is a beast (not tried that yet) and you can crank up on ya bike! When there's snow you just swap out the bike day for a snow sport or feet up with coffee.
