I'm doing it for the first time this year. I got sick last year after Christmas and couldn't ride much in January so didn't try then. I've been riding 3-5 days a week since Christmas and I'm hoping I can handle the tour finally.
Going hard two days in a row with Sufferfest videos is not easy! I'm sure 9 days will feel pretty rough.
Actually, I'm going to use the Time Zones and start on Friday night so I can sneak in a rest day in the middle. Or I might just finish early.
I have both the original version and the new version of Revolver, so I'm planning on using both to ease the mental boredom. It won't make the ride any easier though!
DeepSeaSue, I hope you feel better. Pneumonia is nothing to mess around with, so maybe you can do the rides later if you need more time to recover. (I know not exactly the same, but better than making things worse.)
Chomper, If you have iOS device you can try the app for $10 and see all the workouts before you buy. Actually, there is a 7 day free trial. The website has lots of info on all the workouts to help you pick. I personally like the Interval workouts the most (labeled "Speed") because they have the most variety.
