that event if i remember right, started when i was in the jaycees. humans almost always won, and that is somewhat rough country the race is held in.
as i remember, sort of. there was a lot of beer envolved in the planning of the race.
as a kid i remember my dad who was born in flagstaff in 1902, telling of a annual hopi indian race where they would run from the east side to the west side of arizona in a race. His comment was those short legged guys actually had an endurance atvantage in the long distance runs.
as to the apache, all one has to do is go down into southern arizona in the mountains and you understand why the army wasn't very effective against them. rough country horses couldn' handle it much less the anglo troopers vs. the apache.
