Back in December 2011, I decided that it was time to start losing weight. So what did I do? I made a lifestyle change – not a fad diet. I decided that I would start eating healthier foods and allow myself one cheat day. I also started an exercise program using a treadmill and light weights. I started running 3.5 miles a day at least 4 days a week. After running for about a month, I decided that it would be interesting to keep track of my runs in a calendar view. So, what did I do? I looked for an existing WP7 app that had the functionality I wanted. I found several apps, but they seemed to never fit the bill so I just went ahead and built my own.
