Ian Koe

Coach

Hi, my name is Ian, and I’m an athlete/coach. As an athlete, I compete in the 100m and 200m sprint events. I have loved the sport of athletics since I was a teenager, and the sport has given me so much in so many ways, and has allowed me to live out my dreams in many ways. In return, I wish to pay the sport back through my endeavours as a coach, to help the next generation of athletes.
