The main venue is Romerike friidrettsstadion, an athletics stadium with eight all-weather running tracks.

The park features of two arenas, LSK-Hallen with a full-size artificial football pitch and Skedsmohallen for indoor sports.

The venue is located adjacent to Åråsen Stadion, the home ground of Lillestrøm SK.

The main tenants for Lillestrøm idrettspark are Flisbyen BK and Focus FK in football, and Strømmen IF, Lørenskog FIL and Minerva IS in athletics.

Many Lillestrøm SK members would put down multiple volunteer work hours to make the gravel pitch ready as soon as they could.

[2] Ahead of the 2003 municipal elections, the Labour Party mayor candidates for the municipalities of Skedsmo, Rælingen and Lørenskog, Andreas Hamnes, Terje Granerud and Åge Tovan, proposed that a central, inter-municipal athletics venue be built for Nedre Romerike.

[2][5] The proposal was followed up by the three athletics clubs in the area, Minerva IS, Strømmen IF and Lørenskog FIL, who established a committee.

Several locations were considered, but the committee landed on Lillestrøm idrettspark because of the availability of existing utilities, parking and changing rooms, which would reduce the investment costs.

[2] In the process, Strømmen stadion was rejected because it was undergoing upgrades to receive artificial turf and Marikollen was deemed too remote.

The rest was financed through a combination of betting grants, value added tax compensation and volunteer work.

[8] In 2009, Lillestrøm launched itself as one of six candidate cities for Norway's joint bid with Sweden to host the UEFA Euro 2016.

[7] Skedsmohallen is the main indoor arena in Skedsmo; it is largely used for ball sports, athletics and martial arts, but also sees cultural events such as concerts.

[12] Romerike friidrettsstadion is an inter-municipal athletics venue jointly owned by the municipalities of Skedsmo, Rælingen and Lørenskog.

[11] It features a 400-meter (1,300 ft) long all-weather surface with eight tracks, permitting 110 meters hurdles on both sides.
