A biography of the record-breaking dressage champion Valegro is being published this autumn.

The book “Valegro: Champion Horse” is being launched at the National Dressage Championships in Stoneleigh Park, Warwickshire, on 17-20 September.

Published in hardback by Third Millennium the book has nearly 250 photographs and a foreword by Zara Phillips.

The incredible story of how the cobby youngster became “the best the world has ever seen” is told by Carl Hester.

The 16.2hh dressage wonder horse currently holds the world records for all three types of grand prix competition.

The KWPN dark bay gelding by Negro, out of Malifleur (by Gershwin) is known as “Blueberry” in the stable.

The remarkable horse has a huge following owing to his enormous success with Charlotte Dujardin.

In April Valegro and Charlotte Dujardin retained their World number one title after winning the World Cup in Las Vegas.

Charlotte Dujardin and Valegro performed a flawless grand prix freestyle to take the Reem Acra FEI World Cup dressage title for the second year in a row.

Carl Hester, Roly Luard and Ann Bar’s 13-year-old Valegro finished nearly 10% ahead of the opposition with a score of 94.196%, just short of their own world record of 94.3%.

At the World Equestrian Games last year they won two individual gold medals and a team silver.

In December at the London International Horse Show at Olympia the crowds were thrilled to see Valegro and Dujardin break two world records within 24 hours.

The book’s author and H&H dressage columnist Carl Hester has ridden in four Olympics including London 2012 where Great Britain won the gold medal.

The biography of Valegro is being co-written with Bernadette Hewitt who also co-wrote with Carl Hester the books “Making It Happen” and “Down to Earth Dressage”.
