Worked example
Worked example
A 500m time of 1:45 is a 1:45 split, which is 302.3 watts. At that power the monitor shows 1341 calories per hour.
How it is worked out
The time over 500m is the split itself, so no scaling is needed. Watts equal 2.80 divided by (split ÷ 500) cubed. Monitor calories per hour are four times the watts, times 0.8604, plus a 300 calorie resting allowance.
