The discovery comes in January, when the temperature in the quaint village dips into the 20s and the soccer players show up wearing five pairs of socks.
"You can see who really wants it in the wintertime," said 14-year-old Eva Schram. "You see who is there because it's fun and who is there because it's their passion."
Schram and the other girls playing for Grotta/KR, a U-16 team from Reykjavik, Iceland, stuck around for cold practices year after year, full of love for the game even when their toes were frozen.
As they travel to the annual Schwan's USA Cup in Blaine this weekend for the first time, they're riding the wave of their island country's biggest moment in its soccer history.
For decades, Icelandic soccer, in one of Europe's smallest football nations, struggled to compete with the sports' blue bloods. This summer has been a different story.
The Iceland women's national team is ranked 16th in the world, and it has secured at least a play-in into the 2017 Euro Cup. The men's national team made an improbable run this June to the Euro Cup quarterfinals in the first year they qualified for the tournament, stunning Portugal and England along the way with a smart defensive game.
Schram, who attends all of Iceland's home games, traveled to Saint-Denis for the Euro Cup match against France, decked out in an Iceland jersey and face paint, singing and chanting all the way through.
"We lost 5-2 but nobody cared," she said, joyously. "It still felt like a big accomplishment. Nobody knew we could go so far. Football — it's all anyone is talking about right now."
