At 16, Bertine moved from Tromsø to Sandefjord to pursue showjumping more seriously. After gaining international experience in Belgium, she is now based in Germany, working with Olympic medallist Rolf-Göran Bengtsson. Alongside competing with her own horse, she trains and competes the stable’s young horses.
Representing Norway has been an important part of Bertine’s development as a rider. In 2024, she was selected for the Norwegian Junior Showjumping Team and represented Norway at the Nordic-Baltic Championship.
