Today’s leg in Route to O-Season 2020 is another urban leg from Bergen Sprint Camp – this time from the CitySprint back in 2018. The same leg was used both in the men’s and the women’s course. Thanks a lot to Niklas Profors for the tip.
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). Note that the map still had a contour interval of 5 meters back in 2018, so take that into account when planning your route. If may not be straightforward to see from this part of the map, but control 11 is lower in the terrain than control 10.

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 alternatives for the leg – read on for the analysis below.
Then we take a look at the results from the leg from the sprint split analysis system SPAS (women’s analysis here) which is used at Bergen Sprint Camp. First for the men:
Then for the women:
As you can see, the fastest split time is run on the C-route for the men and the F-route for the women. It seems quite clear that A is the slowest alternative – chosen by two of the top 25% finisher among the women and on top 25% finisher among the men. Alternative B was very popular among the top 25% finishers among the men (7 of them chose alternative B, with Jonas Leandersson as the fastest) and also many of the slower women (7 outside the top 25%), but this alternative is clearly slower than the alternatives to the right (C, D and F), according to the statistics compared to the rest of the course it should be around 10 seconds slower. The reason for it being slower is that you need to run longer in addition to the extra downhill/uphill (compared to F).
It is a bit surprising that alternative E has been ran that fast, but it might be that Frederic Tranchand (the only one running fast on alternative E) just had very high speed here.

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!
