She could easily catch a zebra, but it would be too large to take down: Antelope like the impala are more her size. You might think the cheetah, a predator that holds the title for fastest land animal, would catch her dinner with ease.
Whether it be to catch dinner or to avoid being dinner, nature has molded predator and prey pairs, like cheetah with impala and lion with zebra, so that competition is fair. When all is in balance, predators get enough to eat without depleting their food source, and the ecosystem is in balance.
The impala is not fast enough to win a race with a cheetah but it does have a trick that evens things out. Instead of running full speed ahead, the impala escapes the cheetah by slowing down and quickly changing direction. This insight, plus many more on the movement of cheetahs, impalas, lions and zebras in northern Botswana, was recently published in Nature. This research was lead by Professor Alan Wilson at The Royal Veterinary College, London, and included researchers at Botswana Predator Conservation Trust and Okavango Research Institute, University of Botswana.
Researchers placed remote tracking collars containing Global Positioning Systems and electronic motion sensors on the animals to collect data on athletic abilities like acceleration, deceleration, running speed, turning and stride. Before the team started using this technology, measurements of cheetah speed had mostly been made on captive animals running in a straight line chasing a lure.
Cheetahs can reach 59 mph (94 kph) even when running through vegetation, but they normally run at half this speed. This fits with computer modelling which predicts predators should run only slightly faster than their prey. Slowing down allows them to maneuver better.
Prey have the advantage of deciding which way to go and changing direction a split second before the predator can respond. Cheetahs and lions sometimes succeed at changing their direction quick enough to capture their prey because they are more athletic than their soon-to-be meal. This means cheetahs and lions are faster and better at accelerating and decelerating then their respective prey, the impala and zebra. By testing small muscle biopsies, researchers have also discovered that muscle fibres have more power.

The peregrine falcon is the fastest bird, and the fastest member of the animal kingdom, with a diving speed of over 300 km/h (190 mph).[1] The fastest land animal is the cheetah. Among the fastest animals in the sea is the black marlin, with uncertain and conflicting reports of recorded speeds.[2][3]
When drawing comparisons between different classes of animals, an alternative unit is sometimes used for organisms: body length per second. On this basis the 'fastest' organism on earth, relative to its body length, is the Southern Californian mite, Paratarsotomus macropalpis, which has a speed of 322 body lengths per second.[4] The equivalent speed for a human, running as fast as this mite, would be 1,300 mph (2,092 km/h),[5] or approximately Mach 1.7. The speed of the P. macropalpis is far in excess of the previous record holder, the Australian tiger beetle Cicindela eburneola, which is the fastest insect in the world relative to body size, with a recorded speed of 1.86 metres per second (6.7 km/h; 4.2 mph), or 171 body lengths per second.[6] The cheetah, the fastest land mammal, scores at only 16 body lengths per second,[4] while Anna's hummingbird has the highest known length-specific velocity attained by any vertebrate.
A widely quoted top speed figure of 71 mph (113 Km/h) has been discredited due to lax and questionable methodology.[56] The highest speed reliably and rigorously measured in cheetahs in a straight line is 29 m/s (104 Km/h), as an average of 3 runs over a 201.2-meter (220 yards) course (starting from start line already running).[57][58]
Pronghorns can reach a top speed of 60 mph (97 Km/h) in good conditions, and a top speed of 50 mph (80 Km/h) normally.[56] They can reach speeds of 72 Km/h in a 2-3 Km course.[59] Estimated by observing the odometer when the animal ran at its maximum speed, alongside a vehicle.[56][59]
At distances greater than 400 metres, the human body requires oxygen to sustain such paces, and speed significantly tapers at this point. 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 marathon world record is held by Kelvin Kiptum with a time of 2:00:35, corresponding to 20.99 km/h (13.04 mph). The ultramarathon world record is held by Dean Karnazes, who ran 563 km (350 mi) in 80 hours 44 minutes without stopping.
Open grasslands and savanna are where most wild cheetahs live and where they are well adapted to hunt. In addition to speed, cheetahs use their vision to hunt, from spotting prey from 5 km away to locking their eyes on the prize during the chase. During those high-speed chases, cheetahs maintain their head posture and gaze thanks to their brain receiving information from specially adapted structures in their inner ears. Cheetahs also have a way to stop the glaring sun from obstructing their view. Those black tear marks, also called malar stripes that run down from their eyes down the sides of their face, attract the sun away from the eyes. The same strategy is used by football players who put black smudges under their eyes.
Cheetahs with their high-set eyes are able to gaze over a wide area, with a 210-degree field of view whereas people can see objects within only 140 degrees. In addition to the position of their eyes, adaptations in the distribution of cells in their retina help them scan the horizon with better acuity. Visual streaks are elongated oval regions of higher cell density which may be in a horizontal or vertical direction. The horizontal streak is more common in vertebrates in open habitats where their visual field is dominated by the horizon, allowing them to have a panoramic view without needing to move their eyes as much. Species that inhabit open environments such as the cheetah, pig and deer were found to have horizontal streaks of increased concentration of a certain type of photoreceptor cells.
Cheetahs cannot use their spectacular vision and speed in areas where open grasslands have been taken over thorn bush. Bush encroachment, one of the ways cheetahs are losing their habitat, is a form of desertification caused both by overgrazing and the decline of large mega-herbivores. Moving through thorn bush causes cheetahs sustain eye injuries and they are more likely to consider preying on farm livestock, putting them in danger due to conflict with humans. Bush encroachment also makes land unusable for farming. CCF established the award-winning Bushblok Company which manufactures an environmentally friendly high heat low emission fuel log called Bushblok that is harvested from thorn bush. The program makes the land more productive and at the same time grasslands are restored for cheetahs.
I've been thinking about thr speed that people have in game and started doing the math to see what speeds different animals would directly translate to having in dnd. Assuming that the cheetah takes a dash action to go as fast as possible, 68 mph (the low end of cheetah top speed) is equal to about 99fps. So technically, in a 6 second round a cheetah can move up to 600 ft. I'm assuming most people wouldn't let a character have an animal companion with quite so much speed, however, how much speed do you think is fitting for a cheetah?
The cheetah and racing greyhound are of a similar size and gross morphology and yet the cheetah is able to achieve a far higher top speed. We compared the kinematics and kinetics of galloping in the cheetah and greyhound to investigate how the cheetah can attain such remarkable maximum speeds. This also presented an opportunity to investigate some of the potential limits to maximum running speed in quadrupeds, which remain poorly understood. By combining force plate and high speed video data of galloping cheetahs and greyhounds, we show how the cheetah uses a lower stride frequency/longer stride length than the greyhound at any given speed. In some trials, the cheetahs used swing times as low as those of the greyhounds (0.2 s) so the cheetah has scope to use higher stride frequencies (up to 4.0 Hz), which may contribute to it having a higher top speed that the greyhound. Weight distribution between the animal's limbs varied with increasing speed. At high speed, the hindlimbs support the majority of the animal's body weight, with the cheetah supporting 70% of its body weight on its hindlimbs at 18 m s(-1); however, the greyhound hindlimbs support just 62% of its body weight. Supporting a greater proportion of body weight on a particular limb is likely to reduce the risk of slipping during propulsive efforts. Our results demonstrate several features of galloping and highlight differences between the cheetah and greyhound that may account for the cheetah's faster maximum speeds.
