For those that believe it is impossible for a human being to run a loop-the-loop with just their own power - think again. Mashable revealed on Feb. 21, 2014, that not only is it theoretically possible, but that it actually happened, and it was done by British former gymnast Damien Walters.
PepsiMax sponsored the attempt by the free runner to sprint around a full loop-the-loop while using only his own human strength and keeping his feet connected to the ground at all times.
So, the company got him an old abandoned warehouse and built him a human-sized loop-the-loop so that he could attempt his huge feat. The short video shows that not only did he complete his goal, but it also shows his preparation and numerous attempts.
Once all the math and research was done, Walters learned that he would need to be going at least 8.6 mph at the top of the loop so that he could make it all the way around. With that knowledge and some hard-fought running, Walters made the impossible, possible.
Damien Walters is a former gymnast who has participated in four Trampoline World Championships and even won the world team title. He has done stunt work for numerous films including "Hellboy II: The Golden Army," "Scott Pilgrim vs. the World," "Captain America: The First Avenger," and many more.
Walters also his own YouTube channel with millions of followers and with numerous videos that have over 80-million views.
