I've looked at a couple other online calorie counters and they seem to concur.
BTW...if you have any suggestions as to a better piece of software or an alternative that will save me the monthly subscription to that website...I'd appreciate it.

Outside of the lab, the use of a heart monitor can improve the energy consumption estimate. Polar uses a couple different methods to estimate energy consumption. If you know your VO2max, the Polar estimate is very accurate.

Was thinking about this yesterday- went for an ‘undulating’ 60 mile ride.
I rode fasted. Well - technically I had a good meal the night before ( but not excessive ) Ride til you bonk is usually about 1500/1600 calorie isn’t it? I use that as a benchmark I think because in my running days ‘usually’ I’d hit the wall at mile 16, 17 if no fuel.
However! As I got stronger and presumably more efficient/ fitter I could stretch that out to even 30 mile runs ( god those were the days ) so like cycling, you become more efficient.
I’m saying this because I usually feel the bonk on a hard ride between 50 - 60 miles so I’ve always equated that with around the 1500/1600 calories burned mark. Guessing that on bike however even when power dramatically drops off and you’re weaving zig zags across the road dreaming of bar snacks, you’ve begun burning fat more.
like everyone says there are so many variables - speed, hills, age etc etc but 3400 for 60 feels over the top. Bare in mind a marathon burns around 2600, possibly more if really motoring so I’d equate a 100 mile ride to around the equivalent calorie burn. Having said that is it something like 4 times more burnt cycling up a steep gradient? I think most folk say get a power meter or heart rate monitor for more accurate reading… but overall I’d say certainly no more than about 2000 for a 60 mile ride.

This was a nice trip down memory lane, seeing all those posts from folks who aren't here anymore. Especially nice to see the pre-power meter stuff. And some posts from our current crop of actives.
I wonder if someone will write a corrective to this thread, explaining it all for you, as it were. Or not? Leave the thread intact, an artifact to be preserved in its original condition?
Because why yes, science REALLY can accurately measure calories burned during exercise, but that's a subject for another thread or perhaps a bedtime story for some child, sending them quickly to dreamland.

Tobymessy Welcome to BF.
Typically quite a few of us don't like to participate in old threads since too many other's don't realize that some of the replies that they may be responding to are from members that aren't active or even alive any more to defend their criticism. Sometimes I've seen old bitter arguments unrelated to the question of the OP get restarted again.
If there is something in this you wish to discuss, then maybe just post your own thread and posit something about it.
