Garmin calorie count with / without HRM

craker

Yesterday's commute, 15 miles @ 17.8 m/h on the posh bike = 867 Calories
This morning, same route, same speed (slightly quicker by a minute) on the steel ss = 389 Calories, but I had the HRM strap on.

Have no faith in those numbers, they are clearly bo$$ox.

Also, why is my hack bike, found at the rubbish dump and now single speeded, faster than a 20 speed carbon road bike....?

Who cares it's jolly fun commuting this time of year.

I reckon about 500-600 kcal per hour depending on pace. Steel bikes are faster, its a fact.

Don't forget to set fire to the carbon bike.

I'd say 6-700 at that pace.

Yup - 600/hr at that speed is about right (all things being equal). Garmin's estimates without HRM are absurd. It seems to work on 1000+kcals/hr for me at 30kmh without HRM - total fiction.

my garmin says i burn about 700 calories per hour without the HR monitor and about 350 to 400 with.

it seems fairly consistent though, so it might not say the correct number but it is ok for comparing rides, if one says i burned more calories then i probably did just not by the number it says!
