This year my club hostet a event for the World Maze Race for the first time. The concept is easy. One identical maze all other the world to find the world fastest maze runner. Building the maze was quite easy and surprisingly faster than setting controls on an orienteering map.
I tried two of the training courses and the race course by myself and it was really tricky cause you need to make fast decisions. Looks like most competitors had fun but also trouble to follow the course. Maze running is a quite easy way to introduce people into orienteering and my club will use it definitely more often now.
You can find the world wide results here.
