This insightful conversation also highlights the importance of creatine for those on vegetarian or vegan diets.

We catch up on the racing and news from the weekend. We bring Kiwi Professional Triathlete Kyle Smith back to the show after his recent 4th place at the T100 in San Francisco. Kyle reflects on his personal growth over the last few years plus the challenges he’s faced around health, particularly related to mould exposure and how these issues impacted his performance. We also discuss the evolution and changes in middle distance racing and the importance of maintaining the balance between training and adequate recovery during the pressures of a much longer racing season. The importance of perspective, the awareness of the risks of overtraining and the need for athletes to find their own path in a competitive environment are now key to athletic success.
