It worked!!!!
I did about 300 miles on my Schwinn Airdyne over a five week period ending three weeks ago (I got Lazy, Bored, dis-illusioned....pick one you like). The reconditioning that those 300 miles provided me was greatly appreciated this afternoon on my first commute of the season.
Now it was a short ride of only 3.4 miles on a heavy old Trek mountain bike on studded winter tires, but every so often I'ld glance at the old Avocet Computer and notice I was effortlessly tooling along in access of 16mph., and like I said I didn't feel like I was pushing very hard at all.
Hooray for the Airdyne. Though it is boring and tedious to use it, it works. Boy-o-boy does it work!
