Ben Duffus has an abundance of running experience. After twice representing Australia as a junior at the World Mountain Running Championships, he initially struggled to turn his potential into ultramarathon results. After starting to work with Mile27 in 2012, he reaped the benefits of race-specific training and finished 7th at the prestigious Ultra Trail Australia (then TNF100) in 2013. From there, steady improvement has led to many amazing experiences around the globe through running, such as a bronze medal at the 2014 Skyrunning World Championships.

    With a background in scientific research, Ben values evidence based and up-to-date training methods, but as an athlete also understands the importance of a personalised approached. His passion for chasing for audacious goals overflows to his peers and he is dedicated to assisting other runners as a Mile 27 coach. While Ben is fascinated by, and continues to expand his knowledge about, the physiological side of running, he recognises that the psychologic side is of (at least) equal importance. Hence Ben strives to find out what drives his clients, in order to help them become the best that they can be.

    Ben fell in love with long distance running as a teenager running cross-country and this love spilled over into the mountains.
