Today’s Sunday Route Choice Puzzle is a follow-up to Route to Christmas were more sprint legs were requested. The sprint race “Effretiker OL” was organized in Switzerland today – and as the Swiss federation now has bought GPS-units, there is GPS-tracking available with several top runners.
The course has a special spreading method in the course: Instead of a butterfly or phi-loop, runners are to choose 5 out of 7 controls within the ring between control number 2 and 3. What would be your choice?
The puzzle is as usually first provided without routes – you may take a look at it and think about how you would solve it (if the image is too small, you may click on it to get it larger). Note that the control to the northwest of the 2nd control is at the house corner.
Next you can draw your own route using the ‘Webroute’ below. Think through how you would attack it, and draw the route you would have made. Some comments about why you would choose a certain choice are always nice for the other readers.
Then you can take a look at how the runners solved the “puzzle” – below the tracked runners are sorted in order based on the GPS tracking times. As you can see, the main problem for several runners who lost time (especially Fabian Hertner) was that they had not checked the control description of the control northwest of the 2nd control.
Did you choose a good order? What do you think of this kind of spreading method?
Wrong choice to first control
From this race, it is also interesting to see how Fabian Hertner is much faster than the other tracked runners to the first control by taking a northern route choice. Everybody is probably too busy reading which 5 of 7 controls to choose after the second control….
