how many calories do i riding a bike at very fast speed

Question

I would appreciate if you could answer me the following. I would like to know, how many calories do i riding a bike at very fast speed?

Answer 1

It is possible to estimate the calories burned in riding a bike at very fast speed by using the MET data (Metabolic Equivalent of Task).
But weight is required in order to calculate calories burned.
I use Met Calculations for the following activity: bicycling, 16-19 mph, racing/not drafting or > 19 mph drafting, very fast, racing general (MET= 12).
Calories are per 1 hour of activity(same for male or female).
(man/woman) weighing 50 kg = 600 calories.
(man/woman) weighing 55 kg = 720 calories.
(man/woman) weighing 60 kg = 720 calories.
(man/woman) weighing 65 kg = 780 calories.
(man/woman) weighing 70 kg = 840 calories.
(man/woman) weighing 75 kg = 900 calories.
(man/woman) weighing 80 kg = 960 calories.
(man/woman) weighing 85 kg = 1020 calories.
(man/woman) weighing 90 kg = 1080 calories.
(man/woman) weighing 95 kg = 1140 calories.
(man/woman) weighing 100 kg = 1200 calories.
