I think one of my favorite non-useful parts of various running apps is when it compares my calories burnt to food that you can eat. My run yesterday for instance would be a half gallon of orange juice. Who drinks an entire half gallon of orange juice in one sitting?
Or my last week workouts in equivalence of chocolate:
Total calories burned
3888calories
Food equivalent
144 Dark Chocolate Coffee Beans, 23 Pieces of Lindt Connoisseur Chocolates, 12 Pieces of Godiva Chocolate Truffles, 4 Flipz Milk Chocolate Covered Pretzels
Anyone want to eat 144 Dark Chocolate Coffee Beans with me?
