Real-time runners

I don't know if it's because I love to run or because I love new applications of mapping technology, but I'm mesmerized by this site, which allows you to view a sped-up rendering of all the athletes running the 2016 Berlin Marathon. As the race unfolds, the pack gradually spreads into a lopsided bell curve, with the most competitive runners outpacing the rest by a compelling distance, and a "long tail" of less fit runners stretching far behind the leading edge. The longer you go into the race, the more the curve appears to normalize around the average pace. 


Expect more mapping-related posts as we approach the release of You are Here: Tales of Cartographic Wonders, from SFFWorld. My story "The Shape of the World's Skin" appears alongside the work of 16 other science fiction and fantasy writers.
