6 kilometers

6 kms is the perfect entry level distance. You can participate both individually and in a group. Enthousiasm and some perseverance are sufficient to complete this distance succesfully, especially when you participate in a group: then you can help each other.

The track runs completely over the campus of the University of Twente and is largely unpaved. While you run (or jog, or walk) the course, you will encounter 23 obstacles: see the track.

Costs: €10 (+ €5 if not an SBN member)

9 kilometers light

Would you like to go a step further, but is a combi consisting of 4 tricky obstacles a bit too much? 9 kms light is a nice intermediate step. You do get the longer distance, but the obstacles are bit easier than those in the 9 kms heavy. You need some technique and strength for this distance.

On the part of the track that’s equal to the track of the 6 kms, the obstacles are largely the same. On the part of the track that is solely meant for the 9k-participants, the obstacles are easier than those for the 9k-heavy participants. For example, one swingover instead of three, or ‘apenhang’ instead of ‘enteren’. But would you like to try the harder version of an obstacle? That’s possible!

The track runs over the campus of the University of Twente and throught the Abraham Ledeboerpark, and is largely unpaved. You will encounter 34 obstacles during the course: see the track.

9 kilometers heavy

Are you an experienced survivalrunner, who can manage KSR-level? Then the 9 kms heavy is the perfect distance. You can expect tough obstacles, such as a long ‘apenhang’ above a river, various combi obstacles, and a number of creative obstacles such as a self made apenhang

Please note: there exists a group subscription, but this is only meant for starting at the same time. You cannot help each other during the run.

12 kilometers

New this year, for the real die-hards: 12 kms! You follow the 9 kms heavy course, but you run the loop through the Ledeboerpark (with tough obstacles) twice. You can also expect a bonus. It is expected that the level will be between a KSR and an MSR.

The track runs over the campus of the University of Twente and throught the Abraham Ledeboerpark, and is largely unpaved. You will encounter 46 obstacles during the course: see the track.
