Quick Answer
The pronghorn antelope can sustain speeds of about 55 km/h over several kilometres.
The Full Story
While the cheetah is the fastest sprinter (up to 112 km/h in short bursts), the pronghorn antelope (Antilocapra americana) of North America is the endurance champion, capable of sustaining speeds around 55 km/h for several kilometres. Pronghorns evolved to outrun now-extinct North American cheetahs. Their oversized hearts and lungs, plus exceptionally high hemoglobin levels, deliver oxygen at rates unmatched by other land mammals. Humans, with proper training, are also remarkable endurance runners.
Key Facts
1.Pronghorns consume about five times more oxygen per kilogram than similarly sized animals.
2.They can run at 65 km/h for extended distances.
3.The cheetah can only sprint for about 20–30 seconds before overheating.
