I endurance-ride a seasoned, 13-year-old Arabian gelding. Because of work commitments, I only train him on weekends, about 12.5 miles (20 km) a day. With this minimal training, he has done beautifully in 25-mile (40-km) rides. Although he has completed a 50-mile (80-km) ride in the past with his previous owner, I have not. Am I doing enough training for a 50-miler? I don’t want to overdo or sour him.
Arabians hold their fitness amazingly well, particularly if they have 24-hour turnout. Working two days per week is usually adequate training for an endurance horse, as this schedule allows for plenty of time for the body to repair itself between the workouts, thus promoting soundness.
If the horse has done 50-mile races before and you are keeping him is steady work, he should have no problem with stepping up from a 25-mile to 50-mile rides, even if you are only doing shorter training sessions...
