Many of the rides I go to are at a lower elevation than where I live. I’m at around 5,000′ and when I ride from home I am always going up higher in elevation. The mountains around here all around us go up to higher than 9,000′ so if I want to I can get in a good deal of high altitude training with my horses.
There has been a fair amount of research done on this topic. Below are a couple of studies that are very educational. I find this topic fascinating because I am always interested in learning what else can I do with my horses to help them do better when competing in endurance rides. In addition to improving their performance I am always interested in learning how I can help them speed up their recovery post-ride.
