Hello everybody. I was just reading about horses stamina little bit. I think that if you wanted to make this stamina more realistic, you should consider the speed of the horse. If the horse travel 5-8 km/h, the horse can travel about several tens of kilometres. If the horse go faster 10-15 km/h, the horse travel one hour and then the horse need a rest. If the horse travel 20-30 km/h, the horse can travel few minutes and if the horse sprint (60-70 km/h), the horse travel about few hundreds meters. And also to make it more realistic I would consider the weight of armor, because if you weight less, then the horse gets less tired.
