I thought running a mile at 7 minutes and walking at 12 minutes would burn the same calories, or that is what I had read in some magazines.
So I decided to use my Garmin Forerunner 305 to compare it with heart rates. I did 10 miles at a slow 15.3 mph pace and burned approximately 75 calories per mile. Average heart rate of 93 bpm
Then I did a 6 mile ride at 24.8 mph pace, and burned 88 calories per mile. Average heart rate of 127 bpm.
These are all on the rollers, so it is the same thing as far as conditions go. So, they are similar in calories burned, but not the exact same as far as calculating using heart rate. Since I am trying to do more things in my life, triathlon, duathlon, 10k, half marathon, etc..., I thought I would look at calories burned.
Now how do I make the transition of calories burned per hour to know when and how much to refuel when on century rides or olympic distance triathlons. How much can my body actually take in during an event and should it all be through the drinks, or should it be through food?
