Over the jumps

In the showjumping event, competitors attempt a series of 15 to 20 jumps set out in an arena, usually very close together, and aim to finish it without knocking any fences over.

Some of the jumps are intimidating and if the rider does not get the horse to jump at the right spot the horse will often balk at the fence and refuse.

If the horse jumps too early it can hit the obstacle with its hind legs, too late and it collides with its front legs. Jumps can be on their own or in quick succession, two or three at a time.

They are not too solid to protect the horses, but that means even the slightest touch can bring a block or pole down and cost precious points.

The slightest touch can see a fence knocked down

Riders walk the course before hand to plot the best point to take-off at each obstacle and the quickest route around.

A draw is made to determine the starting order. The object is to complete the course, regardless of style, with the fewest penalties for errors.

The penalty list is as follows:

Four points for knocking down an obstacle or putting a foot in the water jump.

Three points for refusing a jump, six points if it happens a second time and elimination should it happen a third.

Eight points if either horse or rider should fall.

Elimination should the horse refuse at a jump for longer than 60 seconds.

If a tie for the lead occurs then a jump-off takes place to decide the winner. The course is altered, and the obstacles moved or made higher.

In the jump-off, time enters the equation, with riders competing against the clock as well as the course. Should the number of penalties be the same then the person with the fastest time wins.

The Brits

The United Kingdom's best hope in the showjumping is John Whitaker, whose vast experience could see him to a medal.

The competition looks sure to be tough, however, with Brazilian Rodrigo Pessoa, the 1998 World Showjumping Champion, the favourite and Ludger Beerbaum of Germany also heavily fancied.
