Route To O-Season 2020: Day 40

Today’s leg in Route to O-Season 2020 is another highlight from the Czech Republic – a leg from the Czech Championships 2019 in WOC 2021 relevant terrain.

Thanks a lot to Eva Jurenikova for the tip. The women’s course was already used in Route to Christmas (day 5 2019) and Route to O-Season (day 34) – today we look at one of the last legs in the men’s course. below.

About the terrain: This is typical Czech terrain where the runnability in the white areas without stones is very good, but both stones, green and steep hillsides limit running considerably. 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. This leg is towards the end of a tough long distance race, and thus it is “a good opportunity to lose a lot of time” if you are not accurate with your orienteering and/or are very fatigued. Thus for many athletes it will be an advantage to not choose the technically most difficult choice – and also not the physically most exhausting choice. The fastest time is run by Vojtech Kral who runs partly left. Good times are also run on straight routechoices, and even for S-shaped routes (where you go right in the first part of the leg to save climb, and then run left in the other half to exploit roads). Generally, however, good execution is key to not losing significant time here.

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!
