About me

About me

My name is Ida Kyrilis (prior Clark) and I was born and raised in Stockholm, Sweden. My love for exercise began when I started to play ice hockey at the age of 6. When I was 17, I moved to Canada to attend an elite ice hockey academy.  After a year in Canada, I moved back to Sweden to finish school and play ice hockey, during which time I played in Mälarhöjden bregdäng, winning 2 Swedish championships. 


At the age of 20, I moved to the United States to play Division 1 ice hockey at Minnesota State University in Mankato, Minnesota and to complete my undergradute in Exericse Science. After completing my undergraduate degree, I was offered the oppourtunity to stay and complete my Masters at Minnesota Sate University under the guidance of Dr. Robert Pettitt. After completing my Masters, I remained in Minnesota for 2 years, lecturing as an associate professor in exercise science. During this time in the US, I started to study the Critical Power concept and how we can apply it to athletes. 


In 2014 I moved to Exeter, England to attend the University of Exeter where I completed my PhD under the mentorship of Associate Professor Anni Vanhatalo and Professor Andy Jones. My PhD was partly sponsered by Nike, investigating how Critical Power and W' are affected by prior endurance exercise. During my time at Exeter, I  was also afforded the oppourtunity to be one of the researchers on Nike's team for Breaking 2. Our team was responsible for testing 17 elite athletes, taking out the top 3 athletes to attempt to run a marathon under 2h in Monza, Italy. Kipchoge ran at 2:00:25, so close. 


My goal has always been to be able to help athletes with their training to be the best they can be, which is one of the reasons I have moved around the world in my pursuit to learn from the best. I am now living back in Sweden where I work part time as a head coach at Crossfit Täby and run my own business where I help athletes with traning and programing and I also use the 3-min all-out exercise test to predict performance and assist in training athletes.
