Three years ago, still a student at UMD with lots of time on my hand, I went running a lot. One of my companions was my running watch, tracking and recording GPS data of my runs. As data and measurement enthusiast, I quickly became interested in the various type of analysis the running watch website provides. Besides timing, pace, and elevation information the run data also provided, when used as set of multiple runs, insight on my favorite running routes in College Park. However, one important feature I thought was always missing in this system is to give better advice on where the most popular running routes are.
