Nina Derron


I love training with my Polar Vantage V. Whether I do running, cycling or swimming, I will find the right features for the training on my watch. It is also very easy to transfer the data to the Polar Flow app, where I can get additional information about the past workout. The app is very easy to understand. I also like the fact that I can change the settings of the different sports yourself with the "Sports Profiles" tab. The Polar Vantage V fits very well on the wrist and feels light. You don't sweat under the watch, which is another advantage.


My name is Nina Derron and I come from Zurich. When I was five years old, I already did my first triathlon. Together with my sisters Michelle and Julie (The Derron Sisters) I work hard to reach the top of the world in triathlon. The three of us are since the beginning of 2019 proud Ambassadors of Polar. Since I often train together with my two sisters, there are always funny moments. Sometimes we laugh, sometimes we argue, but we are always pushing each other to get better.

Personal best:

9:05:33h (Ironman, 2019)

Pre-race ritual:

Talking to myself. I keep saying to myself: You can do it! You can do it! You can do it!

Proudest sporting moment:

At the Ironman Vitoria-Gasteiz in Spain in July 2019 I did a very good race and finished second. This was the first time I got the qualification for the Ironman World Cup in Hawaii. I am very proud of this race.
