If you're not selected to run WOC 2017 in any of the 50+ part taking national teams, you can take part of the spectator race Estonian Orienteering Week.
EOW has 6 competition days - 2 urban and 4 forest in some of the most beautiful Estonian towns and best forest terrains. A bit of information can be found at: http://www.woc2017.ee/eow/
(more to follow in the autumn).
PS! WOC 2017 host town is Tartu and not Otepää as given in the event location.
