Not continuously, but 52 years and counting. I had a 15 year layoff owing to lack of funds in my 20's and early 30's, but as soon as salary allowed, I was back on 2 wheels. For some 30 years of that time the bike was my sole or primary form of transport and during that time I was a 365 days a year biker. These days I prefer it to be above 45F and preferably dry before setting off. Call me a wimp, but I don't feel I have anything left to prove on 2 wheels.
