Tjurruset - OCR Race 2025

Tjurruset – Extreme Cross-Country Run with a Tradition Since 1992

Tjurruset is a well-known Swedish sports event held in Karlstad, aimed at those who enjoy physical challenges and competing in tough conditions. The main course is approximately 10 kilometers long and features numerous natural and man-made obstacles that require not only fitness but also determination and grit.

The event also includes races for younger participants: Kalvruset (for children aged 9–14) over a distance of about 2.5 km, and Minikalvruset (for children up to 8 years old) with shorter routes and child-friendly obstacles. There is also a team race format called Tjurruset Lag, where the total time of the five fastest team members determines the team result.

The event attracts hundreds of participants each year and is one of the most recognized races of its kind in Sweden. For those interested in group or team registration, the organizers can be contacted via email.
