Grouping of runners: EOC Long Qual

Jan Kocbach May 28, 2008 Events 7 Comments

Did the qualifiers get to the final based on their own achievements only, or did they get help from other runners through either co-working or following? Grouping of runners is always a hot topic at the major orienteering champs. The below analysis of the results regarding runners running in packs from the WOC Long Qualifier is done by Henning Spjelkavik as a part of a work done on separation methods in orienteering (read more about the work here) – and the way to display the material is inspired by methods shown by Martin Lerjen for WOC 2007 results.

Note! Colored boxes in the below figures show that two runners have been within 15 seconds of each other at a control. Being within 15 seconds of each other does not necessarily mean that the runners get help from each other for the orienteering or to keep up higher speed – but if two runners are within 15 seconds of each other in a large part of the course, it indicated that at least one of the runners has gained time due to the grouping. These types of graphs are especially interesting in order to find out how effective separation methods are in orienteering.

Very intressting. Kerschbaumer is able to run the speed of Hubmann (Heat C) over half the qualification race…

I am looking forward to the analysis after the long final. As the start intervall is two minutes we should have lots of opportunities to see if the used separation techniques are working (or not).

time for butterflys etc. in quals too?

What does the numbers within the boxes mean?

AL: Use of a separation method in the qualifiers (not necessarily butterflies though) is an interesting thought.

-: The numbers in the boxes are only there to indicate which runners have been together – a numbering of each pack so to say.

At the Mens Top Ten today… (me looking at the results)

1. Tsvetkov: Together with Efimov (10.) since 11th control, together with Nikolov since 15th control, with Mihalkin since 22nd Control.
2. Hubmann: First contact with Johannson (5.) at the 8th control, running togehter with Johannson from the 16th control
3. Wingstedt: Some not very cooperative contacts with Wickholm. Together with Lucan (14.) from the 13th control (but Lucan always behind)
4. Merz: Ran the whole thing alone
5. Johannson: catched up by Hubmann at 16th
6. Rollier: Ran the whole thing alone
7. Bertuks: Together with Schneider (23.) from the 19th
8. Weltzien: Contacts with Troeng from the 12th, together with Troeng from 16th to 25th
9. Ikonen: with Öhlund (23.) 3rd to 6th control, and 16th to 19th, else alone.
10. Efimov, see Tsvetkov (1.)

Some comments to this:
1) 16th control is at the middle of the race, if two runners catch up there, they are running half the race together
2) I doubt that the competition is fair. See the case of Merz, Rollier and Wingsted (somehow) all considered running alone: Tsvetkov makes the difference from the moment he runs with Efimov. Hubmann and Johannson make the difference from the moment they run together.

So.I have nothing against Tsvetkov, he is the winner. Let’s just put some effort in avoiding that amount of mutual influencing among the top ten of a Championchip.
