Heck, I rode into the light rail this morning all of 14 miles with an average of 13.5 miles an hr and was working my arse off. In summer my average was more like 17 mph with panniers. Now I have narrower tires and a rack trunk. The cold weather is kicking my rear. Anyhow, now that my family has joined a rec center I am seriously tempted to start using the light rail each way to reduce my mileage down to 30 miles each day in Jan-March. Then make up the lost exercise at the rec center. Strangely enough I have found that I do not mind working out indoors anymore. Oh the temptation!
