Athletes from 11 different countries were tested at the World Cup events and European Championships held in Roskilde, Denmark. At the World Orienteering Championships in Västerås, Sweden, athletes representing 16 nationalities were selected for doping tests. The testing programme included a total of 46 tests. The sample analysis was performed by the IOC accredited laboratories of Aker University Hospital in Oslo, and Huddinge University Hospital in Stockholm respectively.

The IOF Anti-Doping Rules have been revised to be compliant with the World Anti-Doping Code and the new rules came into effect on 1 August 2004.

In accordance with the requirements of the Code, the IOF has identified a registered testing pool of athletes who are required to provide up-to-date whereabouts information and make themselves available for out-of-competition testing. The IOF’s testing pool includes the athletes of the national federations’ A-teams in all IOF disciplines, i.e. foot orienteering, mountain bike orienteering, ski orienteering and trail orienteering.
