So, Roughly/exactly, cycling for one hour..
Discussion
How many Calories do you burn?
I seem to find different answers to this question, can any one here give me their best guesstimate?
answers so far include:
- (from a Personal Trainer) around 200 calories an hour
- from my work colleague/and the computer on the exercise bike- 600-700 depending on intensity
- from my road bike's Cat Velo 8, 270-300.
Any advance on the above?
Thanks!

There's too many variables, surely?
On a schoolnight, I only do a five mile circuit round town - but on an MTB with the ever present galeforce winds and the fact 3.5 miles of that circuit is climbing (usually steeply), then I'd be burning more than a five mile jaunt on a roadie in the flat part of the county?
That's my excuse

Depends on the efficiency of the bike and the efficiency of your body. I think Heart rate monitors estimate (or guess 
) the calories used based on your heart rate through the exercise and a guess at how efficient your body is.
The actual number of calories used will be different for people doing the same exercise.

That is a real tough one. I'm 106kgs and to burn 1000 (based on heart monitor thing) would take about an hour and a half of cross-trainer / static bike in the Gym.
But the effort required in the GYM is far less than I use on my MTB to do say a lap of White's Level on my MTB.
Speaking to a guy in Morzine once, he had a funky heartbeat reading watch that showed how many cals he was burning, from when he left the chalet at 10am until he got back at 4pm he'd burnt over 5000 and he was super fit.

Don't have any of my power files to hand (wrong computer) but anything between 400-1000 depending on what I am doing
HRMs don't "know" enough to tell you how many calories you have burned. If you include average speed and cadence into the calculation, it gets a bit more accurate, but it still doesn't consider stuff like gradient and wind speed and is also heavily reliant on how the device calculates it.
The majority of HRM based calorie counters I have encountered will over read by a fair bit - even a power meter (which will measure the amount of work you put into the bike) is out by 2-5% due to the nature of the human body. One thing a HRM will tell you is where the calories are coming from - if you know your zones, then you can work out roughly what percentage you are burning is fat, what is carbohydrate etc.

According to sporttracks (awesome free software for analysing GPX files), this morning I did 28.71km in 56.58m, and burnt 980 calories. Sporttracks records the amount of climbing, my weight, and the weight of my bike, but not the prevailing wind. I know it uses weight in the calorie calc, but whether it uses the weight of the bike, I have no idea.
