Scott first started riding at the age of 7, his Dad used to be a jockey and bought him a pony one day. His list of achievements on the equestrian Team GB website is very long. To name a few, he has won and come highly placed in a number of 3 star and 4 star classes in 2011. At the start of 2012 he won the $50,000 Wellington Grand Prix riding Intertoy Z, a horse he has ridden for a number of years. He is currently ranked 4th out of Great Britain's Show Jumpers.
Scott has a number of horses he rides including Intertoy Z (previously mentioned), Bon Ami II, and Sebastian III. Below is a video of an interview with him before a show jumping competition. He also speaks about the Olympics during the interview.
I am sure we will see a lot more of Scott Brash. He even said he has younger brothers and sisters that enjoy Show Jumping so they may be ones to look out for in the future.
