I've been doing the new commute for over a week now:

   * 3.5 miles to the Oakland Jack London Amtrak Station on bike, downhill.

   * 40 miles to the San Jose Amtrak Station.

   * 1 mile to work, Santa Clara and 2nd Street.

   * reverse, but uphill.

9 miles of biking has turned out to be 10mph downhill, 8 mph uphill, for about an hour total time, averaging 9 miles per hour, which is pretty good, given the stoplights and traffic I have to deal with.

I figure I burn about 300 calories on top of my existing 2200 calories base rate, for a total of 2500 calories.  I think I'm going to see how many calories I eat and track it in gnucash.
