I can't find any real info on ostriches running long distances. The best I've found is National Geographic stating that they can "run long distances at 31 mph". But how far can they run? Humans can, and often do, run 100 miles in one effort. I'm curious if the ostrich's internal system can maintain 31 mph for over 3 hours, or barring that get to 100 miles at any speed.
Pronghorn Antelopes, on the other hand, can maintain speeds of 60 mph for miles at a time. "If the Cheetah and pronghorn were running side by side, and if the track was longer than a quarter of a mile, the pronghorn would win it, no contest," Carmi Penny, director of collections at the San Diego zoo says. While cheetahs have flexible spines which allow their legs to spend more time pushing off the ground, antelopes have long thin limbs that allow them to run both fast and economically. These legs, paired with tremendous aerobic capacity, are what allow the antelopes to outrun most predators. When you get to long distances, the antelopes can sustain 30 mph for about an hour.

This is a video of human hunters (Koi San, an African ethnic group that has been pushed to extinction over the last millennia by the Bantu tribes) chasing down a kudu antelope. Antelope are great runners, but they can't cool themselves as efficiently as humans. It's a beautiful video, and the way the hunter reacts after the kill is very moving.
That is a really cool video but I'm not sure if I'd take that to say "humans are better long distance runners".
The fact is that humans are the most intelligent species (excluding dolphins and mice) and have used that to their advantage. For example, carrying water and weapons. Since these tribesmen can carry water they can replenish water that the other animal cannot. If the tribemen and the antelope had the same amount of water (none) who would win?
Also, I'm not sure if it is the case in this video (also, my audio is not working so I'm at a loss for anything said during the video), it wasn't clear if they were using a triangle approach where you have two hunters on either side and one in the middle. In that instance the antelope might run back-and-forth over that long distance and not run in a straight line (meaning it ran farther, just not smarter).
Even if we disregard the benefits from a higher intelligence it still only says "humans are great long distance runners in hot/flat terrain when carrying water". For example, try out-jogging a deer this December in the midwestern wilderness, or slap on some tennis and try to wear out a husky when it is twenty-below and 30mph winds.

When I read this for a split second I was thinking "man, how can this guy think dolphins are smarter than humans? And mice? What is he think... oohh, Heheh! Nice.
I believe the Ostrich and the Antelope would disagree.
