Today’s leg in Route to O-Season 2020 is leg 5 in the W21E course from Finnish Championships Long 2018 – the men’s course from the same race was one of the finalists in “Course of the Year 2018″.
This race was featured in Route to Christmas 2018 – but then we took a look at a similar leg in the men’s class.
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). This is a long leg. It has paths. It has roads. It has tough uphills – and tough choices for you as a runner. What would you choose?

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. This is a special leg that deserves some comments – please provide your thoughts about the best solution on the leg!
Then you can take a look at how the runners have solved this leg below. As you can see, going right on the road clearly paid off, with the four fastest runners taking the road. This is nearly as for the similar men’s leg in Route to Christmas 2018. The straight/left option is a bit too tough, but still good times are run here. Going all the way around to the left is definitely too long!
Update: Based on some calculations done in the comments, around to the left is too long to have fun, but no too long to run a good time on the leg. Going around to the left on the road should be approximately equal (at least) to Rudnaya’s route. Looking at the speed on the road for Rudnaya compared to Hirvonen, Rudnaya seems to be around 4:00 min/km elsewhere in the course while Hirvonen is around 4:45 min/km for the 4(!) km on road/big path on this leg. This corresponds to around 3 minutes difference, which is the difference between Rudnaya and Hirvonen on the leg. So similar times should at least be possible. Thanks to Jarkko and Terje for their comments!

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!
Going all the way to the left was indeed very far, but do you have a better number for how much it cost? I.e. there were few runners taking that option and if none of them were strong runners it is hard to know for sure! How much did they lose on this leg compared to an average over the rest of the course?
It looks to be about 1.7 times longer than going straight, the difference is less compared with the fastest routes to the right?
Terje, I believe left must ahve been was really good. I compared Rudnaja and Hirvonen with speed hadicap factor based on their pace elsewhere (but Rudnaja still winning course with 1 min) and left ended up being 1 minute faster.

Thank you Jagge! That did at the very least confirm my prediction that female runners can run even further around on flat paths & roads than what the best men can do.
Let’s see if Jan K have any further comments. :-)
I agree that going around to the left on the road should be approximately equal (at least) to Rudnaya’s route. Looking at the speed on the road for Rudnaya compared to Hirvonen, Rudnaya seems to be around 4:00 min/km elsewhere in the course while Hirvonen is around 4:45 min/km for the 4(!) km on road/big path on this leg. This corresponds to around 3 minutes difference, which is the difference between Rudnaya and Hirvonen on the leg. So similar times should at least be possible (but it is definitely boring :)
