The idea to found the new football team began with a birthday party in 2005.
In the 2021 season, the team cruise-controlled through the season, gaining promotion to the 1. Deild for the first time in the club's history. This was the first season that chairman, Arnar Lognberg, was in charge of the team for a full calendar year.
Name
The team is named after its first team sponsor, the Faroese representative of the Icelandic soap producer Undri, which means wonder in Icelandic. It means the same in the Faroese language, however a definite article is added making it Undrið, but the Faroese pronunciation remains the same. (In Icelandic, they would be different).
