Rosanne de Boer (NLD)


My name is Rosanne de Boer (1991) and living in Zoeterwoude. A former competitive swimmer and switched to triathlon since 2015. I lost the pleasure of swimming, but in combination with cycling and walking I got it back!

At the end of August 2015, I did my first sprint triathlon in Ouderkerk aan de Amstel and I immediately took the win.

After two seasons (2016 and 2017) in the 1 st and 2 nd division team competition, it was time for a longer work. Starting with half a triathlon.

May 2017 I did my first half triathlon in Nieuwkoop and the following year three more. That was the NK in Nieuwkoop (and I improved my PR by 30 minutes compared to 2017), my first Ironman 70.3 in Edinburg (I was 2nd and qualifying for the World Ironman 70.3 in 2019 in Nice) and Challenge Almere (3rd in age group).

That tasted like more for 2019. I planned my first Ironman (Cork) and in the run-up there I did a number of games in preparation. During the race, I was in Cork 2nd in my age-group and qualified me for the World Ironman in Hawaii in 2019!

The schedule for 2020 still says:

  • Eredivisie wedstrijden TTW Weesp
  • NK Halve triathlon in Nieuwkoop
  • Brouwersdam
  • Ironman Emilia Romana

In addition to training (or rather in addition to my work, I train), I work at Lifeguard in Utrecht as an HR employee and project manager. Lifeguard helps organisations to become more vital and to perform better in a sustainable way. I am very happy to represent this beautiful organisation.

On to many wonderful (sustainable) triathlon years and I am very happy with the support of AthleteSportsWorld.
