Troy Reneker has been studying the art karate for over 20 years. Born into a very sporting family in the southern suburbs of Sydney, he came to the conclusion very quickly that he was going to dedicate his life to sports achievement. He decided very young that physical fitness was considered one of the most important ingredients in a happy and successful life.  Troy was recognised as being one of Australia’s best sports karate fighters and has represented Australia for more than 12 years. He was classified as an elite athlete with the Australian Sports Commission.

Troy commenced his martial arts training at the age of 10 where he took up Goshin-Ryu karate under Shihan Richard Bradford. He fell in love with karate the moment he started and began a serious regime of practice that saw him train nearly everyday. By the age of 13 he had achieved the level of black belt. But it was the love of competitions that really struck a chord with Troy and he soon found himself inspired by the dream of representing Australia.

A talented rugby player in his youth, Troy was forced to make a choice between his two loves – rugby and karate – and specialize in one if he was to scale the heights that he so desired. He decided upon pursuing a karate career because of the fact that it offered a spiritual side as well as a physical side and he quickly developed into one of Australia’s best sports karate exponents.  He was first chosen in the National Karate Team as a junior and then worked his way through the junior ranks until he was 18 when he made a successful transition to the National Senior Team.

Troy’s international sports karate career has seen him win 13 medals whilst representing Australia. This is made up of 6 Gold, 2 Silver and 5 Bronze medals for both individual and teams events. He has traveled the world with his sport and has competed in high-level competitions in Australia, New Zealand, Japan, South Africa, USA, Mexico, England, Scotland, France, Germany, Denmark, Finland, Belgium, Luxemburg, Italy and Greece. He has also trained with some of the best sports karate athletes in the world and so is up-to-date with the latest tactics and strategies.

Troy’s standing as an elite athlete has seen him spend considerable time training and learning at the Australian Institute of Sport. It is from here that he has learnt the importance of embracing a correct strength-training program to complement a grueling karate and fitness program. Troy is regarded as being a bit of a pioneer in the development of plyometrics training for martial arts training. He is also strongly of the belief that a comprehensive and sport specific weight training program should be coupled with high-level martial arts training. He cites the body’s requirement to perform dynamic and fast-twitch movements in martial arts as the reason why a strength-training program is needed.

Currently ranked as a 4th Dan black belt in Goshin-Ryu, Troy has now retired from the sports side and has embraced the more traditional side of karate. He has trained under the Goju-Ryu system in Australia and Japan and has been graded to black belt by the Japanese Karate Federation. He has trained with Hanshi Patrick McCarthy since the early 90’s while living in Australia but is now resident in Dublin.

Troy has started the first official International Ryukyu Karate Research Society (IRKRS) study group in Dublin and is setting about establishing Dublin’s first dedicated Koryu Uchinadi Kenpo-Jutsu dojo. All are welcome irrespective of experience or style.  Koryu Uchinadi is established as a pragmatic alternative to the plethora of terribly ambiguous and highly dysfunctional styles of "traditional" karate.  Koryu Uchinadi Kenpo-jutsu is a modern interpretation of Okinawa's historic combative-like disciplines. A completely systematized, cohesive and coherent method of learning/teaching, delivered in a traditional atmosphere, honoring both its culture and pioneers, Koryu Uchinadi Kenpo-jutsu is both an art and a science. Based on common mechanics and supported by immutable principles, the most unique features of Koryu Uchinadi Kenpo-jutsu are its vibrant body dynamics, efficacious tai-sabaki, functional HAPV-theory [Habitual Acts of Physical Violence] and application-based two-person drills, which breathe life back into kata.

For more information on Koryu Uchinadi or the IRKRS in the Dublin area please contact Troy at 087-9259445 or e-mail

Troy is available for seminars, long/short duration courses and private tuition on all topics indicated above.
