Picked up a Specialized Allez Sport a few months ago so no more long distance street riding on my mountain bike (yay). I'm getting in shape for a charity ride at the end of this month (100 day 1, 60 day 2) and there is a double century ride happening this summer that I want to do as well. Most I've done in a day is 106 and 200 just seems insane, but I'm going for it anyway.

200 is a long day in the saddle. My longest ride was about 120, but that was several years ago. I am glad my rides are still a few months away. I've not been riding as much due to weather and I need the extra time to shed my winter coat. Rocky Mountain Cycling Club hosts a series of brevets here that sound interesting. I think I am game for the 200k and 400k, but the 1000k might have to wait for another time.
