Found this in "Lidingöloppet", which the same name as the biggest X-country race in the world with 18000 participants in the main race (30km). Two of us run the 30k race on Saturday and the kids run the Girls 10y and 7y race on Sunday. Afterwards we found this less than 100 m from the finish line without any mugglers spotting us. That was a challenge in itself. Very nice coin indeed. We'll take it down to Skåne, the southernmost county in Sweden.
