Your responses are useful for me, too. I haven't taken a sizeable break in years, but I'm scheduled for spinal surgery near the end of October and will be in a neck brace for 4 to 6 weeks. I'm planning to do P-B-P in 2011, so this is probably the best possible time for me to do an extended break, but I imagine I'll be spending lots of time on rollers (or at least on a trainer). But I figure that after close to 40 years of riding (mostly racing), it shouldn't take too long to come back.
