Tim Reed.
PERSONALISED COACHING.
While studying to become a PDHPE teacher, Tim became fascinated by exercise physiology and endurance sports. Tim decided early on he was more interested in endurance sports coaching than becoming a teacher and so knuckled down on learning as much as he could about training for endurance sports while casually dipping his toe into triathlon to gain a very thorough understanding of what an athlete experiences as there is a limit to what a coach can learn from a text book.
-
This toe dipping transformed into a total belly flop immersion as Tim worked his way through the age group ranks and then turned professional at the relatively late age of 25. From there, Tim established himself as one of the more consistent performers on the world long course triathlon circuit collecting over 90 professional podium finishes, an Ironman Australia victory and multiple Australian and Asia Pacific titles. The highlight of his professional career collecting a World Championship title at the Ironman 70.3 World Championships in 2016. Unlike many pros who start coaching as their career earnings drop and they search for alternative revenue, Coaching has always been a part of Tim’s day to day life because he genuinely gets immense joy out of helping others achieve their athletic goals and through the continual pursuit of perpetual learning. Tim has learnt not just through the many athletes he’s coached and the success he’s achieved as an athlete but also from the many mistakes he’s made along the way. We’ve made most of the mistakes so you don’t have to!

Penny Slater.
PERSONALISED COACHING.
Penny has been a sports fanatic from a young age competing at a high level in field hockey and equestrian before picking up triathlon in her early 20s. This coincided with Penny beginning her Exercise Science Degree and Bachelor’s of Secondary Education. As Penny was completing her Uni, she discovered long course triathlon and found a deep satisfaction from the work ethic required to compete at a high level.
Over the next few years, Penny began moving through the ranks as a professional, securing multiple Ironman and 70.3 podiums. At the same time, Penny’s fascination with Exercise Science grew and she began research into applying science backed coaching approaches to her one-on-one triathlon coaching. She enjoys the challenge of tailoring training to an individual’s physiology and commitments outside of training
-
Outside of racing and coaching, Penny is very passionate about research in triathlon. After struggling with Relative Energy Deficiency in Sport (REDs) and its subsequent consequences, Penny began some postgraduate research to understand more about the topic and its effect on athletes particularly female athletes. Fast forward a few years and Penny is deep into her PhD looking specifically at REDs in triathletes and how it can be managed and prevented, with some of her studies being published in late 2025.
Penny is deeply passionate about wellbeing of athletes being at the front and centre of performance, as a happy athlete is a fast athlete.
