Discussion: WOC 2010 in Trondheim, Norway

As many of you may be aware of, Trondheim in Norway will host WOC in 2010. Some information on location and embargoed areas (also with some English text) is available on http://home.no.net/stok/ (see upper left corner).

This weekend, the Norwegian Night Champs, Junior Relay Champs and the Final in the Craft Cup will be held in a neighbouring area, approx 10 km north of the main embargoed area. Link to the organiser's website is http://www.ntnui.no/ogruppa/nm2006/ (the student club in Trondheim). The information is only available in Norwegian, but after the events you may browse maps from the event, and get some motivation for preparing for WOC 2010. The terrain during the weekend is however at slightly higher altitude, and is a bit more marshy than the WOC 2010 terrain. Hope you will find some useful infomation during the next few days, (and learn some Norwegian words for your 2010 preparation).

I remember Trondheim terrain as being very nice (and very detailed). Good route choice terrain while also requiring fine navigation. Good footing, but lots of moss and marsh running.

The races in Trondheim have now been held. Maps, route choice and some comments can be found at Oystein Kvaal Østerbø's homepage; http://folk.ntnu.no/oysteios/ Note the 2500 meter long leg to the 4th control, this was a leg where several of the favourites lost time.

What's up with 5-6-7-8? Looks like one wing of a butterfly loop.

The course was forked (controls 5-11). This was explained to the runners in the PM for the race, see http://www.ntnui.no/orientering/nm2006/?p=pm_natt (sorry, only available in Norwegian, and I am too lazy to translate).

I'm too lazy to translate, but I read the explanation and looked at the maps. It is fairly simple (if I understand it correctly).

Note that OKO's 8-9-10-11 is the other part of the loop. The order for running the two looping options alternated - so the even numbered starters got one loop first, the odd numbered starters got the other loop first.

If I understand the PM correctly, the runners got both maps at the start and instead of a map exchange, they just turned the maps over at what would be a map exchange. I'm not certain about that. It depends on what the Norwegian word "snur" means -- it sounds like it'd mean turn over.

OK. I hadn't noticed that #6 and #11 were the same control.

Thanks for the translation. It is right that the runners got both maps at the start. At control 8 or 9 , depending on the loop, the runners turn over the map bag. It seems to be a clever forking system. In previous Norwegian Night Champs, "following" has been a problem issue.

Here's the map with the loop drawn in:



I have no idea what these are called, but I call them "Theta Loops" because they remind me of a greek theta "θ".

I think of the first variation as going around the outside (in this case clockwise), then going across the center and out. This map is the second variation where the runner goes across first and then around the outside (again, clockwise) and then out.

I wonder how they printed the other map, specifically if both variations turn over the map at the same control?

The forking method we used is essentially the same as described here:

cool, neat & interesting..& fair

I thought Norwegians didn't follow...

They used this type of forking method at the WC Long distance race in England last year. I liked it, but the loops (legs) were relatively short and you had good visibility, which meant it wouldn't/didn't (?) break up packs very well.
