Today’s leg in Route to O-Season 2020 is a leg from part of the embargoed area for WOC 2021 in Czech Republic. In 2016 a Czech national race was organized on this map – the INNVO-8 Cup. The 17th leg in the men’s leg was an interesting route choice leg which is chosen for this edition of Route to O-Season 2020
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. The leg is around 2 km long, and running around on the road to the left is around 800 meters longer than the straight route. Still, the route around proved to be faster, with three of the fastest routes being run all the way around on the road, and most of the fastest routes being run either all the way on the road or partly to the left on paths/fields. Of the alternatives to the left it is definitely faster to choose the road, though. Straight can be executed with a quite limited timeloss, as shown by Jan Sedivy who is 50 seconds behind the race winner (and fastest on the leg) Jan Petrzela on this leg, compared to four minutes behind in all of the race.

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!
