We've partnered up with the team at Longines Global Champions Tour to give away dozens of free tickets to 2015's show jumping event of the year.

We have 20 pairs of tickets to give away to go along and see Great Britain's Olympic show jumping heroes John Whitaker, Ben Maher and world number 1 Scott Brash in action against the rest of the world. Ben took the title in 2013, but can he do it again?

The event, taking place at Syon Park from Friday July 24 - Sunday July 26, will see top riders competing for prize money of over £600,000.

Each day will feature top-level competitions featuring the highest-ranked riders in the world with the Longines Global Champions Tour of London Grand Prix taking place on Saturday afternoon (July 25).​

This will be a fantastic event with plenty of fun family entertainment, from pony rides to scurry racing, a shopping village full of delights and delicious food and drink on site to enjoy.

Competition closes on Wednesday (July 22).
