This website allows you to export your run data from Nike+ so you can import it into programs or other websites like Strava or RunKeeper. The data is exported using a format called GPX, which is a common exchange format for GPS data. Heart rate data is included when available.
Due to changes on Nike's part, this site needs a major overhaul. It will be back in early 2013.
