Davy Suvee uses Neo4j to graph his running data from his Garmin Forerunner


When I started running some years ago, I bought a Garmin Forerunner 405. It’s a nifty little device that tracks GPS coordinates while you are running. After a run, the device can be synchronized by uploading your data to the Garmin Connect website. Based upon the tracked time and GPS coordinates, the Garmin Connect website provides you with a detailed overview of your run, including distance, average pace, elevation loss/gain and lap splits. It also visualizes your run, by overlaying the tracked course on Bing and/or Google maps. Pretty cool! One of my last runs can be found here.

Apart from simple aggregations such as total distance and average speed, the Garmin Connect website provides little or no support to gain deeper insights in all of my runs. As I often run the same course, it would be interesting to calculate my average pace at specific locations. When combining the data of all of my courses, I could deduct frequently encountered locations. Finally, could there be a correlation between my average pace and my distance from home? In order to come up with answers to these questions, I will import my running data into a Neo4J Spatial datastore. Neo4J Spatial extends the Neo4J Graph Database with the necessary tools and utilities to store and query spatial data in your graph models. For visualizing my running data, I will make use of Gephi, an open-source visualization and manipulation tool that allows users to interactively browse and explore graphs.
