Route To O-Season 2020: Day 71

Today’s leg in Route to O-Season 2020 is another urban leg – again we visit Bergen Sprint Camp, a race series where there is a lot of analysis available for the courses. Thanks again to Niklas Profors for the tip – this time we took the trip back to 2015.

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). The same leg was run by both the men and the women. Note that back in 2015 there was 5 meter contour interval on this map (and the leg is all downhill):

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 the different alternatives below.

SPAS was used for analysis for this race (men / women), so we know a lot about who took which variant. Here is the analysis from the race day:

B/D are good choices and nearly equivalent. E and C gets too long, and loses you time. A was also thought to be too long, and based on the mens splits it also looks like that. The women do however have the same leg, and there Lind wins the leg with the A routechoice. Of the top runners Fraser (5th overall) loses 13 seconds, Deisz (9th overall) loses 19 seconds and Alelinuas (12th overall) loses 18 seconds. None of these have stated which variant they ran in SPAS,but based on the GPS it looks like they ran something between D and A. Estimated time losses: E 8-10 seconds. A and variants of Fraser/Alelinuas 8-10 seconds. Difficult to estimate C as very few run there.

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!
