I see now that my guess of 4,000 was rather optimistic. It was probably
something around 2,100 and it was from 33 miles of cycling (230 lbs @
15mph = 966kcal/hour x 2.2hrs = 2125)


At 230 lbs running costs abou 165 kcal/mile. Cycling uses about 1/5 of
that. So my guess is more like 1100 kcal to cycle 33 miles.



I entered
140 minutes at 230 pounds and it suggested 1800 for moderate stationary
bike and 2700 for vigorous stationary bike. Real cycling usually ends
up a bit less strenous that on the stationary for me because on the
stationary I make sure to maintain a minimum heart rate. The 2100
number might be an okay estimate.
