The course, with 16 control points, has opened at the Regional Park in Ballincollig. The project is a joint initiative between the Cork Orienteering Club and Cork County Council.
The council is hoping the course will prove a hit as orienteering is growing in popularity.
A council spokesman said the sport was enjoyed by individuals and families and was becoming more popular with schools.
Orienteering is a race against the clock which involves people using a map to navigate a number of control points. The person or team which make all the checkpoints in the quickest time win.
A map of the route is available to download on www.corko.net
The course, which was used for the first time last Saturday, has been sponsored by Margaret Long of Cafe Chico.
John Scannell was the quickest around the course for the inaugural race, making all 16 controls in 29 minutes, 14 seconds. Therefore, he has set the course record.
Francis Harrington came in second in a time of 31 minutes, 24 seconds, while Ken O’Neill claimed third place on 37 minutes.
