This is amazing: Undrafted Robert Gill of the Arizona Cardinals attempts to give the treadmill a run for its money.
During a workout with teammates he challenged the treadmill by running at a speed of 40 km p/h. Gill waits on the side of the treadmill, prepares himself, and then sets off. Gill may only have run on the treadmill for all of eight seconds, but his legs will remind you of the cartoon character the Road Runner.
And if you thought nobody could reach such high speeds, you would be wrong. At the 2008 Olympics, sprinter Usain Bolt reached a speed of 43 km p/h.
