Ever since the start of Strong Viking in 2013, our editions are not a race but a challenge. It’s all about pushing your limits and overcoming obstacles together. An important part of all Strong Viking editions is having fun together! To also introduce less experienced athletes to Strong Viking, we will introduce a new distance: BEGINNING (4km). The obstacles you will encounter on this course have been carefully selected for this new distance. The obstacles are especially fun and focused on cooperation.

The obstacles you encounter on this course have been carefully selected for this new distance. The obstacles are especially focused on fun and corporation. You will not encounter any extremely difficult or heavy obstacles. It’s all a bit less technical and has a very high fun factor. Do you not dare an obstacle and/or are you afraid that you will not succeed? No problem! At every obstacle there is a possibility for a by-pass, where you can skip/walk around the obstacle! But… since we always try to push you to your limit, always try to challenge yourself before skipping!
