You probably burned less....I'm M, 46, 6'1", 239 lbs. I rode
41 miles in 3 hours. My polar told me I burned 2990
kcals...fitday.com said 1990, and this cyclist software said
1890 or so...all of them are probably over estimating.

Since your weight sounds good for your height, and age
(actually very good), why, may I ask are you interested in
calories burned?

The body is -very- efficient. Most people don't realize how
much work it takes to burn even a small meal. It's good for
us to have such efficency for survival reasons, even if it
is perplexing for dieters.

PS great job on the ride!! ;-) How long have you been
riding? (it takes me a week to get to 100 miles!)

I don't personally take any of the calorie expenditure
values give by the various machines at face value. You go to
the gym and get on a treadmill for 20 minutes, it tells you
that the cals burned was something ridiculous like 600. Then
you get on a ergo rower and do a solid 40 minutes and it
says 300 cals.

Perceived exertion is invaluable here.

This is true. It's amazing. You can run like 10 miles on the
energy derived from one apple or something like that. The
body is -incredibly- efficient.

90% of trying to train physical appearance is diet, IMO.

What do you have your VO2max set to? Polar's calorie
computation depends heavily on the VO2max setting.

Here's some recent data from my Polar for comparison:

Distance: 111 mi. Vertical: 5000' Av. Speed: 17.0 mph Av.
Heart Rate: 124 (69% of max.) Energy Expended: 644 kcal/hr
VO2max: 68

644 kcal/hr seems about right for me (I'm 5'11", 135 lb.).
It might be a little low, actually, but not by much. My
VO2max may be a little higher than 68, but I haven't yet
ponied up the $200 to have it tested.

400 per hour is reasonable for your size, depending on the
amount of wind and climbing. I'm about 150 and need 500-600
for normal moderaly hard rides, and 900 for race level
efforts. Go to analyticycling.com for more info.

Probably you are. 400 calories per hour is a lot of energy
to maintain for 6 hrs if you're not a pro level rider. Your
energy expenditure doesn't change a whole lot with
temperature until it starts getting very cold, at which
point your energy usage goes up to try to keep your body
warm. It just feels a lot worse, and you lose a lot of
weight due to sweating.

Well yeah, that's the obvious answer, but you should

-B,

I need to keep track precisely to keep my svelte 125 lbs.
It took me almost 2 1/2 months during the off season to
get that low. Now that I am riding 250+ miles a week, I
need to know how to adequately fuel without adding
bodyfat. It's really hard unless you know how much you
burn during exercise.

PS-been riding since the 80's, with a hiatus for

Hmmm. I set it at the recommended default for F's, which was
35, since I have absolutely no idea what it really is.
Something to consider.
