In today’s leg in Route to O-Season 2020 we again travel to Halden and the ongoing GPX-cup.
The leg is as usually first provided without routes – you may take a look at it and think about how you would attack this leg (if the image is too small, you may click on it to get it larger):

Webroute
Next you can draw your own route using the ‘Webroute’ below. Think through how you would attack this leg, and draw the route you would have made. Some comments about why you would choose a certain route are always nice for the other readers.
Then you can take a look at how the runners have solved this leg below. Note that some runners had the control to the right, but still all runners ran through both controls, so timewise the time difference should be small (but the ones having the control to the right did not have the possibility to choose the best route to the left). Thus this setup can be used to look at both the control to the left and the control to the right. To the leftmost control it seems like left is faster, although Lundanes is somewhat faster than Eliasson and thus the difference is maybe not as big as it may look. To the control to the right it is clearly faster to run direct – around the lake all the way to the right clearly seems to far. What is your opinion?
Density map
See below for a density map of some of the ones who have drawn their routes so far (available during the day when some readers have drawn their route).

Route to O-Season 2020 series
Route Choice Challenges while waiting for the real action: With the upcoming orienteering season indefinitely on hold in large parts of the the world due to COVID-19, regular orienteering route choice challenges may be one way to make sure those orienteering skills don’t get completely rusty. I’ll try to keep these coming daily, but need help from all of you out there to keep them coming and to keep up a certain quality.
Tips on good route choice challenges – either from races/trainings (even cancelled ones) or theoretical ones with accompanying analysis – are very welcome (please e-mail to jan@kocbach.net).
Not all legs are taken for the interesting routechoice alternatives – some are also taken because the map is interesting – or because it is not straightforward to see what to do on a certain leg. Any comments are welcome – especially if you ran the event chosen for todays leg!
OL used 73:32 whereas FE used 87:29 for the course. Compensating for OL’s better orienteering the speed of FL is still some 50 s slower pr km, or 9-10 minutes for the course or 50-75 s for this leg. In this view, FE’s route-choice may indeed be a little faster than OL’s. Interestingly, it seems that perfect execution of the left route-choice is not that much easier than semi-right, both MD and SA loosing time by poor execution of the left route-choice. That SA beats OL on one part of the left route-choice leg is also very interesting, probably the extra climb SA gets is less than it may appear on a the first look, OL is actually a bit lower in the terrain than SA.
