That over heating and muscle mass is a huge difference.
They tend to be built like wrestlers, lots of big bulky muscles which as you stated don't lend themselves to cooling.
Once again Joe - you are generalizing. The heavily muscled QH are not suited. But neither are the fine boned halter Arabs.
My QH gelding was an awesome distance horse. He settled in better for longer distances. 50 and 60's showed his best readings when I did competitive. He placed in the state and the region when I was active in the sport.
Build says a lot - but so does heart. My guy has a ton of heart. I stopped distance riding due to time and finance constraints. I still go on conditioning rides with my stock horses.
