Cats are not made for endurance, they are ambush predators and rely on fast sprints. I guess outrunning horses is much more of a feat but even then if you are slower it's kind of useless, that goes for cats as well, if you can run longer than a cat but so slowly that even they can catch you before running out of breath then it's pointless. And it's even more useless if you can only do it in hot weather and it may also depend on the breed of horse too, there are probably horses that can run for much longer than the ones they are using. I'm not sure about their conclusion on distance either, yes, humans have been known to run marathons and even super marathons but these super marathons are usually over short time spans that people train years for, they probably could not run 100km a day everyday all year. However migratory ungulates do run long distances all year and maybe you could find longer running examples of them, they also don't run for as long as they can but only as long as they need too.
