Drafts weren't built for speed nor stamina, so they're one of the most unlikely types of horse to ever be successful at endurance. As was stated, endurance is about long distance stamina. In order to have a chance at endurance, you must be on a horse that can trot the entire day without getting tired. On top of that, for longer rides, you really want a horse that not only can trot an entire 50 miles without even flagging, they must be able to lope short distances as well. It's all about strategy, and the right amount of speed you need to be a contender.
Obviously, Arabians dominate endurance completely, at least in the upper levels. At lower levels such as 15 mile pleasure or even 25 mile limited distance, most breeds can compete and have a good shot at winning. Half-Arabs are obviously the next best choice, but Mustangs are also making a name for themselves as good strong endurance horses. I've seen a decent amount of winning on stock horses as well.
An odder breed that most people don't own or even know of is the Akhal-Teke. They can pretty much equal the endurance of an Arabian, but just aren't used a lot. We had the chance to meet two young ones from Ontario at an endurance race last year. They're an extremely athletic and sporty breed with extreme stamina.
