Derin was born in 1994, and started riding ponies when he was only 4-years-old – at the Galatasaray Pony Club in Istanbul, Turkey. He has been passionate about riding ever since.
When he was 10-years-old, Derin started competing with horses in the children’s category in Turkey. When he reached the age of 12, he got selected for the Turkish Children’s Team and started representing his country in international competitions.
With the Children’s Team, Derin won three consecutive team gold medals at the Balkan Championships (2006, 2007 and 2008) and a team bronze medal at the European Children’s Championship in 2008. After a very successful start to the 2009 season, he was selected for the Turkish Junior Team. The same year, thanks to his many good results in international competitions, Derin qualified for the European Championships for juniors.
The year 2009 was a special year for Derin: Although his first year as a junior, he won four international Grand Prix classes! The same year Milliyet and Cumhuriyet – two major national newspapers in Turkey – honoured Derin by nominating him as “Sportsman of the Year”.
In 2011 Derin was placed in 24 international competitions, and he won 12 of them. What made the year 2011 unforgettable, was the individual silver medal at the European Championships for juniors which he won on his horse Madick in Portugal. It was the first time in Turkish equestrian history that a junior won a medal at the European Championship. After such a successful year, the Turkish Equestrian Federation awarded Derin as “Most Successful Junior" of 2011.
