So I got the "mapmyrun" app.
I go for a walk at lunch today. Nothing stannous as I don't want to be hot and sweaty getting back, but just something to stretch my legs and see the sun.
2 miles, leisure walk, app says I burned 370 calories.
I get home and change, whip out the poorly geared fixie, go out for a 25 minute ride, come back sweating, red faced and breathing hard. App says I burned 190 calories.
WTF
