The calculations this website uses for calories burned, pace analysis, power output, etc. are based on a mythical “typical” runner: a 35 year old who weighs 150 lbs with a Maximum Heart Rate of 190 beats/minute, a Resting Heart Rate of 50, and a Threshold Pace between 9:12 and 9:30 min/mile. The good news is that you can customize the results and graphs from GraphMyRun by entering in your own personal information below. (The information you enter will be stored in your browser. It is never uploaded anywhere and is completely private.)
