I am trying to find a calculator or equation that accurately estimates
calories burned. I have been using the formula of 0.28 cal per pound
per mile, but I am suspicious of the results I get with this.
For example, right now I weigh 250 lbs and can do roughly 21 mph over
a 40k course ( mostly flat, about 500ft climbing total. Also, on a
standard road bike, normal position, no aero bars, normal wheels ).
This would put my calories per mile at 70, and per hour at 1470.
However, if I weighed what I should, 170lbs, to burn the same amount
of calories I would need to average almost 31 mph.( which would make
the calories even higher! due to more wind resistance) Now, I should
be able to burn the same amount, if not more so at the lower weight,
since I've only been training recently for 2 months, so I suspect
either 0.28 is too high or I will be national TT champ next year ( not
too likely, my best 40k was only about 55min at fighting weight. and I
am now 41 yrs old)
Does anyone know of a formula that can adjust for speed as well as
weight?
