Running is a sport that you get while the getting is good, and it has not been good for me most of this year. Holidays, bad weather, and, for the past few weeks, an achy left knee means I’ve been running way less.

I’ve been riding our indoor bike a lot as a replacement, but it’s just not the same, especially when it comes to calorie burn. I track my weight & calorie intake using Macrofactor (mentioned here), with the magic of math and good nutrition science it makes a fairly precise guess of how many calories you burn a day, using nothing but your scale weight and the number of calories you eat.

See if you can spot when I started running every day, and when I stopped. It’s amazing how quickly it picked up the trend, and how drastic the drop was. (There’s about a 500 calorie spread between the top and the bottom of this graph.)
