I went through the usual bigger-bikes-as-I-got-older thing as a kid but pretty much dumped my Columbia Tourist when I got to high school, began distance running in earnest and like most teenagers waited until I got my driver's license. Bought a Schwinn Varsity to commute to a summer job and for the past 40+ years have alternately ridden or run until tearing a meniscus last summer (surgery Sept 28) and finding that the beginnings of arthritis in that knee means.....I have the opportunity to ride more and run less(!)
