AIR-DEFLECTING SHIELD ALLOWS ATHLETES TO RUN LIKE THE UNIMPEDED WIND

Summary from the TLDR newsletter

The Airshield is a device that allows runners to train without experiencing any air resistance. Currently a prototype, the Airshield allows athletes to run faster than they are able to unaided, allowing their bodies to learn the neuromuscular sequences required to run at that speed. The wedge-shaped open-backed cart is towed behind an electric go-kart, which is steered along a running track by a human driver. Pictures and a video of the Airshield being used are available in the article.
