This treadmill could snap an Olympic sprinter in half before he hits the first minute. Because it's locked to a real world record marathon pace and almost nobody survives more than a few seconds without collapsing. So for years people swore that speed was flat out impossible for a human body to handle. But then they put actual pro runners on it, guys who race for a living, and it dropped them just as fast as everyone else. And one man stepped up claiming he could hold that exact pace for two straight hours. When he did, he didn't just survive the treadmill. He became the first human being alive to break the two hour marathon. Via @gqsports on YT #running #treadmill #marathon #sports #shorts
