The week you posted looks great. Just right if you can recover well, which you must be doing. That's what I always did: go hard on the weekend and just build endurance during the week. Stoker and I have been on vacation and missed 3 weeks of biking. We did get up and run for 20 minutes every morning, had one weights session and one spin class. We did a metric century yesterday, our first outing and not too bad, 4:10 saddle time. About 3000' of climbing. We rode with a couple other tandems and a strong single, who gave us a nice 21 mph pull on an 8 mile flat. We were TTing it just to stay on! I find endurance fades more slowly than strength. Stoker's legs are sore today, but we'll go for a hike. Should help.
My back seems to be getting better and Medicare paid for the MRI that my private insurance refused, so I'll finally find out what's wrong and what to do about it other than complain.
