Factual error: The race ends at Damascus, which is nowhere near the ocean, yet is placed on the seacoast.

Continuity: Near the end of the race, Hidalgo collapses and there is blood in his nose. Then, when Hidalgo has gotten up and is running full out towards the finish line, there is no blood there at all. In the next shot, there is a pinkish trickle of blood that goes about to Hidalgo's chin.

Continuity: In the final leg of the race, after Frank has taken the saddle off of Hidalgo, there are many shots of Frank riding Hidalgo. In one of the slightly wider shots that shows Frank, Hidalgo's back, and Hidalgo's neck, you can see the back of an English saddle under Frank's butt, even though he's supposed to be riding bareback.
