The Journal

The Castore Sporting Journal brings you behind the scenes insights into the world of elite sport. We seek out individuals and organisations who have demonstrated proven performance excellence over a sustained period and aim to understand what it is that gives them their edge.

Calvin Betton is the founder of the Calvin Betton coaching academy. He has worked with numerous national level senior professional players who have competed in Grand Slams and the Davis Cup, as well as a number of world ranked junior players on the ITF Futures and ATP Challenger tours.

Kayvan Seyri is the lead strength and conditioning coach of England Basketball and has been working with the team in their build up to the Rio Olympics.

The ability to achieve result beyond what your resources should reasonably allow. It’s been the panacea of elite sport since, well, forever. Equally, underperforming despite vast investment and expectation has always been equally baffling.
