It was another slow week for riding, what with cold weather and a lot of things going on.  I had planned a 70-mile ride for today, but one of my shift levers broke to the point where I can’t shift and I can’t repair it myself.  Plumb wore out, they tell me at the bike shop.  It’ll be Wednesday or possibly Friday before it’s fixed, so I’m stuck riding the mountain bike for a week.  That’s not a bad thing, really, although the mountain bike is not made for hours of road riding.  I’ll probably spend the week doing one-hour rides.  Maybe find a tough hill and do “hill repeats”–ride up the hill, rest on the way down, repeat until legs are rubber.  That kind of workout is not recommended more often than once a week.
