Been out the last two nights at 9pm to do a 5 mile with 900 ft climb run at under 10:30 minute mile. Crazly I have dropped two Kg since Monday morning, RunKeeper reckons that run is worth 780 calories does anybody know a rough formula for calculating calories burnt during a run?
I know the only truly accourate way is to take a blood sample to measure the sugar content in the blood
