What should the avg KJ....?

[Witrot]

What should the avg KJ burned be for a training ride of lets say 50km or 100km on an avg HR of 75%??

I just want to clear this up for myself, cause i think my HR monitors values is a bit of. I no it various between different cyclists, but i just want to get an idea more or less.

 

If anyone can help me out?

[I FLY]

At that HR % I normally use 650kj/hour.

 

I weigh 77 kgs.

I am closer to 1000 KCal/Hour @ 75%, but I weigh 100kg (on a good day...).

I burn almost 500kj on the 13km (35min) commute to work.

[Evan Andreou]

At 75% I ave round 900KJph

[Frosty]

At 75% for a 3-hr training ride, I burn about 800kcal/hour.

At 85% for a 3-hr race, I burn about 1000kcal/hour.

 

Weighing in @ 85Kg.

what is the differance between kcal and kj

[sias]

1 kcal = 4.18 kjoule

 

Altwee is die hoeveelheid energie verbrand maar die Polar werk op kcal...

 

Ek verbrand tussen 600 en 800kcal per uur op 75 - 80% hart tempo.
