The second World Orienteering Day (WOD) is scheduled for tomorrow (May 24).

WOD gives local orienteering clubs an opportunity grow their membership and expose more people to the sport through work with schools, local organisations and sport authorities.

The IOF has said their aim is to attract primarily young people to partake in orienteering for the first time in their life.

This view was echoed by Haldna, who has set ambitious targets for this year and next.

"We, the IOF, National Federations, clubs and our enthusiasts have to work together in order to archive our common goal, 350,000 participants in 2017 and to reach 500,000 participants in 2018," the Estonian said in a post on the IOF's website.

"WOD is a unique opportunity to promote our sport globally and locally at the same time.

"There are already now pre-registered events from 17 countries and territories who are not IOF members.

"This shows a great potential to increase our membership."

Last year's inaugural WOD was marked by the IOF opening their new headquarters in Karlstad in Sweden.

The governing body had decided in 2015, as part of its strategic plan, to close its offices in Helsinki and relocate to Karlstad.

It was estimated that more than 200,000 people in over 2,000 locations in 79 countries took part in WOD.

The IOF also received a letter from the International Olympic Committee (IOC) President Thomas Bach who voiced his support for the event.

Tomorrow will also see the opening day of the first World Cup round of the season.

Action is due to begin in Turku and Lohja with the sprint relay.
