Grouping of runners: EOC Long Final

Posted by Jan Kocbach, 29 May 2008@12:00

grouping.jpgAt the EOC Long Final yesterday, runners running together in packs was a big discussion due to the fact that most of the men within the top 10 probably had some use of other runners to keep up the speed and lower their errors. The below analysis of the results regarding runners running in packs from the WOC Long Final 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. Boxed in the same color show that two runners are together. In each box, the position the runner has at this control is shown.

Updated 2008-02-06: Now the runner who is first in the pack is marked with bold. Also, a tooltip is shown which shows how much a runner is behind.

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.

Please add your comments below! There is a lot of material for discussion here!
