My goal for the year was to displace 3,000 miles of car travel. To me, this meant 3,000 miles of trips that I would have made anyway in a car — commuting, errands, etc., so recreational cycling wouldn't technically count. I feel like I've gotten pretty close, no matter what the rest of the year looks like. I'm particularly happy in comparison to last year, when I cycled only about 2200 miles, over 500 of which were weekend recreational miles. (Nothing wrong with them, except they don't displace auto miles.) I got a late start this year, no cycling in January, which was pretty inclement, and precious little in February. I'm just going to have to get out more in winter if I want to make my goal next year, which I'm setting at 3,300 miles. (You read it here first.)
48 weeks* x 5 days x 17.6 miles in my RT commute = 4224 miles per year at 100% utilization.
(* I figured 52 weeks - 3 weeks vacation - 1 week holidays)
Seriously, I do a good amount of business travel, which should fairly be excluded. And there are other extenuating circumstance -- no one should have to cycle in a downpour. Not only is it not fun, it's dangerous. But I know that by US standards, I'm a cycling fiend. It just goes to show that the bar for defining "cycle commuter" has not been set too low by our friends in Congress.
