Max calories burned in an hour

fteale

What is the maximum number of calories you can burn in an hour? At the moment, I cannot burn more than 540 in an hour, that is off road running including sprints, HR 168 average (my 10k time is 52-56 minutes). Doing circuit training it's more like 450 an hour. Both cases I am working flat out as hard as I can.

I am always interested in how people can burn 1000 cals an hour.

So what's your hourly calorie burn?

My burn depends on what I am doing. When I run that is my max burn. My heart rate is around 155-165 when I run. I burn 720 calories in 70 minutes. So I average 100 calories every 10 minutes. I cannot get this burn rate from anything else I have tried.
