Rungsted Ishockey Klub were founded on New Year’s Day 1941 and are one of the oldest active ice hockey clubs in Denmark. They have played in Denmark’s first tier throughout their history, only dropping to the second tier on a few rare occasions. They are regarded as a strong and traditional team that regularly participate in the playoffs and compete for trophies every season. Throughout their history they have won five Danish Championships. Today they go under the name "Rungsted Seier Capital".

They have won two championships on the bounce under new head coach Erik Hjalmarsson. In 2018/19 Rungsted finished top of the Metal Ligaen with a league high of 149 goals in the regular season. Their strong form carried them all the way to the playoff finals where they faced SønderjyskE Ishockey. After four decisive wins they were crowned champions of the league for the first time since 2002.

In 2020/21 they once again won the regular season and the playoffs in decisive fashion, beating the Aalborg Pirates 4-2 in the finals series and qualifying for the CHL.

Rungsted first secured Champions Hockey League qualification for the 2019/20 season. Despite finishing bottom of their Group and missing out on the CHL Playoffs, they recorded a win on home ice against HPK Hämeenlinna on the final game day. They are qualified for 2021/22 and will make their second appearance in the league alongside fellow Danish club SønderjyskE.
