The IOF has published revised competition rules for foot orienteering, applicable from July 2008.
Changes to the 2007 revision are mostly applicable to IOF events. The only significant change to rules affecting general competition is new rule 24.15 (The results must be based on competitors’ times for the whole course. No changes may be made to these times on the basis of split times). Although OA rules have not yet been updated to reflect the IOF changes, the intent of rule 24.15 is to remove the option to adjust times where problem legs occur (a misplaced control, for example).
Previous guidelines recommended that times not be adjusted in such circumstances, but rule 24.15 explicitly disallows such an adjustment.
