Advent calendar day 17

Now the competition for the title as winner of the advent calendar has sharpened up and I have received several answers on the main question. Still nobody has cracked the calendar and the answers so far are wrong. Maybe that changes after today? Well anyway, here is today’s question. For some days ago an orienteer named Kristian became number 12 at the European cross country championships in Tilburg. In the team competition his team received a silver medal. This was Kristian’s second medal this year at the European championships. The first, a bronze at the sprint in Ticino earlier this year. I want the name of his birth land, where the orienteering association is called Cymdeithas Cyfeiriannu Cymru.
