Well, I got to tell you, Hip, today was a reality check. Yes, you may not have any downhill sections on a trainer or at the gym so you need to keep peddling continually but roads are harder, I don't care what anyone says. I just did a simple loop of 4 1/2 miles and I was winded. I had a max heart rate of 156 and I was on easy gears.
Also, I am riding one of my brothers old bikes. The first time I got on it I felt like I'd never been on a bike before. I've had bikes my whole life but they have always been "Two-ton Schwinns." If you wanted to turn left you pushed your right hand forward and the bike turned left. Not this bike. You want to turn left you drop your left shoulder a quarter inch and WHAM! You are tearing thru a turn. And the shifters are on the diagonal tube. (Until I get my balance skills back I intend to keep it in only one or two gears. Every time I shift it is an adventure.) If it were a boat it would be called 'tender.'
I got used to it but it took a while (a few hundred miles) and I'm starting over again at square one. I asked him about it when he first gave it to me and he described it like this. "You're used to a 75 Chevy Impala. Some big block, gigantic old boat that cruises down the road. Now you're driving an MG. Smaller, lighter, faster and much more responsive." After I put several hundred miles on that first summer he let me take his new bike out for a spin and it was the same thing all over again. "Now you're going from an MG to a Ferrari."
At least my arse feels ok. The saddle didn't really have a chance to cause me misery, I was on it for less than 15 minutes. My hands didn't like the brake hoods, either. Man, that stationary bike at the Y is starting to seem like a waste of time! Winded, tachycardic and sore after a 4 1/2 mile ride. Reality check indeed.
