Cricket may seem like a slow game, but the distances covered by mainly fast bowlers are great.  Fast bowlers cover more distance than half marathon runners at times. Recently during a Boxing Day, Ashes Test Match, Mitchell Johnson was recorded as having covered 23 kilometers on the first day.  He also reached speeds of 33.1kph and this was achieved by chasing a ball to the boundary.  The fastest speed recorded using the Australian GSP monitoring system, was done by Brett Lee, who reached a speed of 36kpm.  This is faster than most wingers, in AFL, rugby league and union.

A fast bowler is generally said to cover about 15km in 50 over cricket (including the walk back to the mark) and more than 20km in a day for a Test match.
