The valley of Groruddalen had a long history of competition between the many football teams.

[3] When the umbrella team Groruddalen BK was finally founded, Høybråten og Stovner IL had also joined.

In its first active season, 2003, Groruddalen BK won their Third Division group with flying colors.

[6] In 2004 they won the Third Division group again, but this time they beat Jevnaker IF in the promotion playoff.

Groruddalen had no grounds for existence as a Third Division club, both because of finances,[5] and because the cooperating parts (Grei, Grorud, Vestli, Furuset, Høybråten og Stovner, Rommen and Romsås) were not backing the club enough.

For instance, Grorud signalized that in a 2009 Third Division season, Groruddalen would be their direct competitor.
