Today’s leg in Route to O-Season 2020 is the longest leg in the women’s class in Junior World Orienteering Championships (JWOC) Long 2017 in Finland. The chosen leg is the 11th leg.
Note that the longest leg in the men’s class in this event was already presented back in Route to Christmas 2017 – but the men’s leg was longer.
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):
You find other maps from the area in omaps.worldofo.com here. See also latest additions in 3DRerun from this area in order to learn more about this terrain type.
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. The leg is kind of an “artificial routechoice leg” where the course setter tried to make the fastest route to the right on the road not look too tempting. However, he didn’t quite succeed, and around 70% of the runners got tempted by the road. It is possible to run straight and not lose much time – Aebersold who was fastest on the leg running on the road would probably have been fastest also on the straight choice. The course setter Jani Lakanen put it this way in his analysis:
– I ran both routes quite even, but I knew that straight will be tougher to execute well. I believe Simona could have done it same time also straight.
Maybe the leg is too evenly balanced when straight and around is planned to be approximately equal? You will save some power going around on the road, and the risk is also lower, so in that regard the balancing is maybe fine with around to the right being the better choice ….
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 email@example.com).
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!
