Consider commuting by bike. It takes dead time--commuting--and turns it into training time.

Intervals are great training, and stoplight sprints during the commute are great intervals. (I race the cars--and sometimes I beat them.) Then, ride right past your house and do your usual one hour loop. Now you've not only expanded your cycling time, you're doing it twice a day, and you've added intervals.

And don't start on me with the "but I have to be presentable at work" excuses. So do I. I haven't missed a day of bicycle commuting since July 2006--and I live right across the lake from you.

My workday doesn't start until after lunch, so my workout miles are on the way to work. In the three seasons, my work week goes like this:

• Mondays are hill days. Loaded panniers (a week's worth of work clothes, lunches, and snacks, plus library books to return) and riding a line of rolling hills to work--some seated, others standing. I'm negotiating use of a gate key to add a seminary on the top of a hill to my commute route.
• Tuesday is my long flat loop (no panniers). It starts by heading six miles in the wrong direction from work. Then it circles around and overshoots by a couple of miles before doubling back.
• Wednesday will be hills again, but without panniers.
• Thursday will be long and flat again, but with panniers to bring home the laundry and more library books.
• Every night is stoplight sprints on the direct route home. There are 20 stop signs or stoplights on that route. Whether the light is red or green, I win. If red, I get to rest. If green I get to crank.

Fridays are variable. They can be rest days, errands days or morning rides with the club. Saturday and Sundays split. One will be a rest day and the other a club ride day.
