Yep. The stride of the guy in the suit is way too long. When you're sprinting, you want to be taking short, fast strides that propel you forward and not rely on your momentum to carry you there. The general idea is that you raise your knee with your lower leg pointing downwards, and then rip backwards, extending your leg as you do so. You don't want to go up at all, just forward. The other thing to do that he's not is move your arms more efficiently. Your elbows should be locked at about a 90 degree angle, and your hands should be relaxed. Your arms drive your legs, not the other way around. (I ran indoor track when I was in high school. My main event was the 55m dash.)
