Can a cross country horse cross over to show jumping?

A cross country event is a type of competitive horse riding event which is run over a long course (6km) that has fixed jumps (as compared to show jumping where the rails can be knocked down).

The maximum height of jumps is 1.2m but they can be quite big spreads (deep to jump over) and can incorporate water and strange objects to test the horses' trust of the riders. The course is over relatively natural countryside, but is groomed to minimise the risk of injury.

The competition is for the lowest score. A long time to complete the course, and refusal of the horse to go over a jump all add to the score.

The horse and rider can also be eliminated from the competition for several things, including: the rider falling more than once, the horse falling to the ground, and for jumping any part of the course in the wrong order or direction.
