Route to Christmas: Day 14 2015

Day 14 in Route to Christmas takes us to Denmark – and a long leg with many route choice options. The chosen leg is leg 25 in the M21E course from the Danish Championships Long organized at September 13th 2015. 

Denmark is country number 14 in this year’s Route to Christmas – thanks to Johan Aagaard for the suggestion!

Danish Johan Aagaard introduces the leg as follows: – Even though the terrain is not as exciting as many of the others you have showed, the leg 24-25 i quite interesting. Especially because the runners pick 4-5 very different routechoices.

One can also add to Johan’s introduction that the leg is interesting because the two best runners in the race had very different strategy on this leg – and one of them failed. Can you find the best route on this leg?

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 terrain is typical Danish. Very fast in the white forest (see picture of the forest here), the light green is quite fast, but the darker green should be avoided. Note that the contour interval is 5 meters.

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. First an illustration with all the different route choices. The two fastest runners overall, Bobach (winner) and Nørskov (second) had approximately the same running speed, but go very different on this leg. As you can see Nørskov going left (but not all the way left, rather cutting through the forest) is nearly a minute faster than Bobach going straight. Thus direct is clearly bad – left is clearly fast. More details below.

First let us compare the two similar left routes of Nørskov and Schøning. Nørskov is fastest on the leg, but loses time to Schøning three different places where Schøning cuts through while Nørskov goes around. Thus Schøning’s route is actually faster, and Bobach’s direct route is even some 15-20 seconds slower than left.

 

Then take a look at Boesen’s route going even further to the left. Here it is clear that Boesen and Nørskov have approximately the same running speed – but cutting through as Nørskov does is approximately half a minute faster.

 

Then take a look at Djurhuus going right. This route is only 80 meters shorter than Nørskov’s route – that’s simply too much when you look at that slow part both around control 36 and towards the end of the leg.

 

Finally the comparison between Bobach and Nørskov. Here you can see that the extra uphills is what really costs time at the direct route.

Additional analysis by Johan Aagard:
In addition to your route analysis it looks like we could elaborate a bit more on the difference in routechoice between leg winner (Nørskov) and (Schøning). Maybe Nørskov just wanted to run as much as possible on the road or maybe he were in doubt if the “Cultivated land” signature were Out Of Bounds?

And if we follow this thought trough Nørskov could have been aproximately 19 seconds faster (If have crossed the cultivated land, as Schøning did), and in that case he would have been not 37 seconds, but only 18 seconds from the gold medal (as a first year senior).

The Out of bounds diskussion is still on going in Denmark (Orientering.dk), and there is many different opinions.
If we look at the ISOM 2000/a>

The signature: 415 Cultivated land Cultivated land which is seasonally out-of-bounds due to growing crops.

In the instruction for the actual race it says:
Out of Bounds areas is marked with black Vertical marking on the map. And acutally the middle part of the field is marked as out of bounds, as you can se eon the actual map in top of the analysis.

The conclusion must be that Nørskov still wouldn’t have taken the Gold medal if he had crossed the “cultivated land”. But if we add the fact that Nørskov unfortunately had forgotten to sign up for the run at the right time, and because of that were not seeded and had to start as one of the first runners.. (No tracks in the forest)…..he could maybe have been even closer to his first Danish Senior Long championship.

Route to Christmas series

The Route to Christmas series at World of O has been very popular the last years – giving the readers the opportunity to do one Route Choice Challenge each day from December 1st until December 24th. If you have got any good legs in RouteGadget, GPSSeuranta or 3DRerun from 2015-competitions – or old forgotten ones which are still interesting – please email me the link at Jan@Kocbach.net, and I’ll include it in Route to Christmas if it looks good. Route to Christmas will not be interesting if YOU don’t contribute.

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!

    Day 14 certainly?

    • I made it two “Day 13″, as a protest to all airline companies and others who skip number 13 :)

      (Thanks, fixed it now)

    Thank you, i have just made som additional analysis :-)

    • Thanks a lot Johan! I’ll add this to the article!

      • Hello again Jan

        I can se that maybe some of the many runners making routechoices maybe have found an even better routechoice than the runners at the day.

        I dont know how difficult it is to make, but if it is possible to compere the routechoice (PACE WISE) by Nørskov, and Dyrhus (Right), with an Dyrhus alternive that goes all the way right and crosses the “cultivated land” most to the right..(as some of the runners in here have done)..maybe Dyrhus could have been the 27 seconds faster……and won the leg ? :-)

  3. Really great article but I gotta comment on this.
    To Johan’s extra comment. Yeah, I did simply not know if I where allowed to cross. I couldn’t remember reading anything about it in the bulletin before hand, but I didn’t want to risk anything.
    And I certainly did not catch up anyone! I did this race completely alone. I forgot to enter the competition in time of the entry date so I got to start as the first guy – between 1 and 1,5 hour before the other medal contestants (1.12 before Eskil).

    But thanks for a great analysis Kocbach. Always enjoy christmas with stuff like this!

    • Thor

      I must compliment your run. It was extraordinary as your run at world cup final.
      Offcause you schould not take that chance if you were not sure……..but it was just to show that also bulletin´s can acutually be important regarding routchoice.

      What do you think of the “All the way right alternative” (All the way right on the open field).

      Johan

      • Hi Johan,

        Thanks! I guessed I was more surprised than everybody else at the World Cup!

        It’s completely my own fault that I didn’t read the bulletin properly and I will do that in the future!

        I think going right on the fields is slower. You get more climb in the beginning and the fields wasn’t that fast compared to a road for cars. Eskil’s line is for sure the best! But it can be difficult to “make yourself go that much around in Denmark”. Usually straight is fastest but when the hills get to steep it’s slow.

        /Thor

        • Hi Again

          I agree with you, but we are just not used to use the fields in Denmark, and we have to be better at following the rules, and not let our “usual” opinion decide for us. And if the fields is for real out of bounds, we should all rember to write it in the bullitins.

          Regarding the right routechoice, Djurhus only loose 27 seconds and he is not using the fields, but running zig-zag on small tracks with small hills underway. (Maybe Rasmus dident even consider using the fields as well)?

          Merry Christmas…. :-)
