Dan Plews is an Applied Sports Scientist, Researcher and coach. As a Sports Scientist (specialising in the area of Physiology) Dan has worked closely with athletes who have won more than 25 world and Olympic titles in the sports of rowing, kayak and triathlon. Athletes include Mahe Drysdale, Lisa Carrington, Eric Murray and Hamish Bond. As a researcher, Dan completed his PhD in the area of applied heart rate variability (HRV). This work focused on implementing and validating methods regarding the application of HRV to track training adaptation in elite athletes. Since then, Dan has gone onto having more than 21 peer-reviewed publications in the area of applied sports science. Dan is seriously passionate about endurance sport, particularly Ironman triathlon, where he has coached 3 athletes under the 8-hour barrier. He lives and breathes it, and is a competitive Ironman athlete himself. In 2018 he broke the amateur course record at Ironman New Zealand by more than 10 minutes in a time of 8 hr 35 min. Dan thrives on continuous learning and being on the cutting edge of applied sports science. He often throws himself into the depths of new science, measurements and self-quantification to find out first hand the effects that they have on training adaptation.
