Damien Walters is a very fast runner that was able to defy gravity by running in a loop just like Sonic the Hedgehog does in the popular video game series. The attempt to run in a loop was sponsored by PepsiMax. Based on the math, it was determined that Walters needed to run at 8.6MPH. The video shows how hard it was for Walter to succeed. In the first few trials, Walters used mats to fall onto. After he got better and better, the mats were removed. Check out the video above.
