There is no one specific breed that is best at trail riding, or that is easiest to train. It is a matter of the individual horse.
For a trail riding horse, I would advise a naturally calm, almost lazy horse. Gaited horses are perfect for trail rides, as they are much smoother and a more comfortable ride than non-gaited breeds.
I know that Tennessee Walking Horses are credited with being highly intelligent, calm, willing animals. However, many breeds are credited with this, and it still depends largely on the horse.
The easiest horses to train are not lazy, but not easily spooked. Rather right in the middle, or close to it. They are also very intelligent. However, horses like this are very rare, so it will be quite a job to find one matching that description.

The Oregon Trail did not start at Indianapolis. It started at any of several "jumping off" points on the shores of the Mississippi River. Common starting places included St. Joseph, which had the furthest west train service of any trains in the 1840s. From that point travelers would start riding horses, mules, oxen and/or wagons to get to Independence and Kansas City, Missouri, on the western side of Missouri state.
the easiest way to train strength would be the Soul Wars minigame.
they train horses that are wild or unruly
People train horses for a variety of reasons and each has their own individual opinion on what they like about horses and why they train them. Some like to train horses to be able to say they've done, others just like working with them on their own, it really does depend on the individual person.
The same way you do when the horses are not in the olympics.
It depends. The horses start at 5 years of age. some horses are learn quicker than others, just like us, but generaly it takes a good 10 years of hard work of both horse and rider to get to the most advanced level.
