Unleash your talent

Duncan is a Performance coach working with athletes preparing to perform at international and national competitions, focusing on mindset, mental skills and sport science to optimise performance.

World-class athletes can feel pressure to perform.

They can feel nervous before competition.

They can have days where they don't want to train.

They can have 'bad' days or moments, and make mistakes.

They question their worth in team selection.

What makes them world-class, is the skills and techniques that they use in response to these moments.

Athlete's of all competitive levels share similar experiences, from international level through to club level.

At DSF Coaching, we lead athletes of all levels all over the world to power their mindset in competition and in training.

Founder, Duncan Foster combines formal training and 15 years proven impact in Coaching, Sport Psychology and Sport Science.

Duncan Foster

I live for the energy of preparation and competition.

I love the relentless pursuit of better. 

I love my role as a coach - consistently driving you to be confident and assured in how you will perform. 

I am fiercely loyal and intensely invested in your development and for you to achieve more and to succeed. 

Outside of coaching, I look for different training and events to challenge myself physically and mentally. 

I have a phenomenal close support network who I adore spending quality time with.

I played football to a decent level in the USA, playing for the #2 ranked team in the country in college soccer. 

I've now moved on from football and into a variety of events as I strive to see what my body and mind are made of.
