Today’s leg in Route to O-Season 2020 is from another recent orienteering activity in Scandinavia – this time a long distance training in Sweden last week.
Thanks a lot to Børge Pedersen for the tip. Børge writes:
An interesting long distance. Course setter Thierry Gueorgiou.
Here we look at the leg to the 14th control. 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. One could assume that Simon Imark (fastest on the leg) was simply running faster, but based on the rest of the course he might have been having a slightly higher speed, but compared to Liland, Krusenstierna and Ridefelt who took routes to the left and right the speed difference seems to be smaller than the difference on this leg. Thus, straight – when well executed – should definitely be considered faster on this leg. The reason for this you can see at the speed comparison on the third illustration. Going straight is flatter than the other alternatives while runnability is generally good. You can really run fast through nice and open forest all the way across the powerline. Then it goes a bit slower in the first part of the green, but it is possible to find good runnability at the edge between green and marsh. On the route to the right it takes more time to get to the path due to the hills and stones there – and going back from the path to the control is not clean and fast either. On the route to the left the path is not flat (and doesn’t seem fast either?), and Ridefelt is also a bit unlucky that the open area just after the powerline seems to be slow.

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!
