Among the fastest animals in the sea is the black marlin, with uncertain and conflicting reports of recorded speeds.
[2][3] The larger reported figures below are therefore highly questionable: 240–320 km/h (150–200 mph)[47] The highest reliably measured running speed for ostriches is 61 km/h (38 mph), obtained by speedometer reading when a car was chasing an ostrich in a straight line chase to force it to move as fast as it could.
[54] A widely quoted top speed figure of 71 mph (114 km/h) has been discredited due to lax and questionable methodology.
The mile run world record is held by Hicham El Guerrouj with a time of 3:43.13, corresponding to 26.25 km/h (16.31 mph).
The world record for longest distance run continuously is held by Dean Karnazes, who ran 563 km (350 miles) in 80 hours 44 minutes without stopping.
