More pedal power to anyone who hops on their favorite two-wheeler and takes off down the highways and byways of Northern California or the mean streets of Los Altos. I have no idea how anyone actually completes the Tour de France, let alone the Tour de Grocery Store.
It seems to me that recreational cycling is a much better way to get around the Bay Area while doing your part to squelch the petro-burning damage done every time the key turns in your gas-guzzler. Cardiovascular conditioning is one positive that comes from those uphill climbs. Putting more muscle on the legs makes for quicker breakaways from your local Peloton and elicits the occasional wolf whistle.
