well, this is exactly what I wanted to know. I got my kewel GPS started today and started watching our speed to see what he does now. I was trying to get him to trot slower ...his most comfortable trot is around 7.5 mph ...so you are saying no, dont go slower? Do they go that fast and faster for 50 miles? What is the average speed of an average endurance rider? Is it alot of changing gaits or mostly trotting at a steady speed?....and yes I know up and down hills, rough terrain, etc makes a difference...but all terrain being the same would you go a steady speed or change gaits more often?
