Route to Christmas: Day 2 2012

The second day of Route to Christmas 2012 takes us to Norway and the Norwegian Championships Long. The race was organized on September 13th close to Oslo. Todays leg is leg number 13 in the H21 course.

The leg in question was in the second half of the course – a long leg in very hilly terrain. Your challenge as an orienteer is to answer the classical “over or around”-question twice – what would you do? 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 who have drawn their route choice solved this leg below.


Comments

The leg can be divided into two distinct parts. The first half of the leg it seems very clear from the GPS-data that direct is no-go – all runners going direct loose time. On the second half of the leg the picture is not that clear – but still direct seems somewhat faster than going around.

Omdal hits several cliffs, and looses 10-15 second going up and 25 seconds going down

This leg proved to be quite decisive in the race as this was were Hans Gunnar Omdal lost the victory to Carl Waaler Kaas. Omdal’s 42 second lead at control 12 was turned into a lead nearly as big for Waaler Kaas at control 13 – just about the same as the winning margin of Waaler Kaas in the end.

Omdal’s biggest mistake was to choose the direct route in the first part of the leg – as you can see from the third illustration above, Omdal lost around 40 seconds on this part of the leg – mostly due to the tough climb. On the second part of the leg Omdal chooses approximately the same route as Waaler Kaas, but has a bad micro-routechoices. Omdal hits several cliffs, and looses 10-15 second going up and 25 seconds going down (not reading the position of the cliffs accurately enough?).

Note that the 12th control is a water control – some runners used some extra time here to find their routechoice (which you can observe on the GPS-tracking).

Route to Christmas series

The ‘Route to Christmas’ series at World of O has been very popular the last years – and I have therefore decided to continue the series this Christmas as well. If you have got any good legs in RouteGadget, GPSSeuranta or 3DRerun from 2012-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!

Note that there may be some errors in the Routegadget data (sometimes somebody draws a route for another runner just for fun). Please add a comment below if you spot en error.

Today’s leg in Route to Christmas is a long leg from the largest individual orienteering ...

  1. The route choices of Kaas and Weltzien, i.e. around or across the final hill, are probably (nearly) equivalent:

    Audun W was not quite in shape this day and lost quite a bit of time to Kaas and Lundanes on the uphill part of the final loop, he commented after the race that he had to select route choices that gave as little uphill as possible.

    • @Terje: It might well be that they are nearly equivalent, but from the material available I still think direct is the fastest. My analysis is not based on comparing only Kaas/Weltzien. I looked at many pairs of runners who were approximately equal on the first part of the leg. See for example Lucasen and Sagberg where Sagberg looses by going around, being approx equal on first part. Also Juveli/Helgerud etc.

  2. Hi, i’ve studied this leg before and RC’s, and the northest one was good too, but unfortunately the map was cut there, so people wasn’t able to see. I think Lundanes did that route choice.

    • @David: None of the one with GPS in H21 took further north – but there might have been others.

      BTW: Lundanes wasn’t running at all :)

      The choice of going norht was actually very bad. I can tell that, because i did it myself. I know Eirik Rustad and Vegard blomseth did the same, and we all lost a lot of time. I guess we lost about 2 minutes…

  3. :D Sorry, my mistake, don’t know why did i thought that.
    Thanks for the correction ;)
