Dr. Daniel Plews  Ph.D. 

 

 

  Dr Dan Plews was brought up swimming, cycling and running in Yorkshire England. Triathlon and endurance sport has always been in his blood, having competed in his first swim run event when he was just 9 years old. Now, he lives in New Zealand, Auckland and is thankful for the similar hilly terrain there that he was used to when living in Yorkshire.

 

Dan won the 2018 Ironman World Championship Age-Group, was the 1st non-professional athlete to finish and set a age-group new world record of 8hrs 24mins. (Videos here)
 
  He has a PhD in exercise physiology from AUT University, Auckland where he specialized in the use of heart rate variability to monitor training adaptation. He also has more than 20 peer reviewed publications in the area of sports science, nutrition and performance.  With a long career in multisport, he has competed in many triathlons over various distances with a personal best time of 3 hr. 55 min of the half Ironman distance and 8 hr. 54 for the full Ironman distance.
 
  As well as an athlete and sports scientist, he also coaches other professional Ironman athletes including Tim Van Berkel, Jan Van Berkel, Caroline Steffen, and rower turned cyclist Hamish Bond.
 
  Dan has been taking the lower carb approach to performance since 2012 after a lifetime of the typically high carbohydrate diet which is prevalent in most athletes. He admits that the terms hitting the wall or “bonking”, as it’s commonly known, never really made any sense to him knowing that there was certainly enough fuel available from a metabolic standpoint.  After doing some more reading and following much of the work done by Tim Noakes, he understood that you can oxidize fat at higher rates of 1.6 g/min. At such rates, you could easily run under a 3 hr. marathon with no CHO contribution at all, so why do we “hit the wall?”. Such knowledge certainly changed his way of thinking, and he accordingly looked deeper into the low carbohydrate approach. After some strict changes to his diet, he himself pushed his max fat oxidation to 1.4 g/min, which meant even at 300 w of cycling, 50% of his energy was coming from fat. This had some huge positive implications for his Ironman race performance, and the whole area of lower carbohydrate performance for ultra-endurance has fascinated him ever since. 
 
Dan is a busy man trying to fit in work as a researcher, sports scientist, and coach, and he is always looking to find ways to maximize his own training. When he’s out training, he’s always looking to gain the most out of every session.
 
He’s found that SFuels is the perfect snack to tick all the boxes.
