Hillerød

During the 1920s, the Danish trade union movement had introduced a new work day structure, consisting of eight hours of work with six weekly work days (compared to the previous situation of 10-12 work hours with 6-7 work days per week), which was a noticeable change, giving the Danes a lot of extra spare time and starting a wave of health interest across the country. Vagn Christensen — a high school teacher in the period 1936–1940 at Grundtvigs Højskole located at Frederiksværksgade 119, who had previously been on the first Danish gymnastics team sent abroad to perform — noticed an interest in the local community and the idea of establishing a sport club, using the school's old, little gym hall as a base, grew in the fall of 1936. To get a better feeling of the local interest, Vagn Christensen and a small group of initiative takers invited a wide range of interested parties for the first real meeting, which was held on 12 December 1936 at Frederiksborg Højskole (since 1937 known as Grundtvig Højskole). Due to the huge interest present at the meeting, a decision was immediately made to form a work group, consisting of Niels Jensen, Oskar Petersen, Marie Madsen, Martin Petersen and Linda Sørensen, who were tasked to design the new laws and just one day later call for an additional founding meeting of a new gymnastics club. The club was officially founded on 11 January 1937 at the club's first general assembly meeting held at Grundtvig Højskole and was named Ullerød Gymnastik Forening (abbreviated UGF), reflecting the club's location at the district of Ullerød in the western part of Hillerød and the primary sport activity among its members. Dairy worker Niels Jensen became the club's first chairman.

A few months after the foundation, the gymnastics season for the club's three first teams was over. With spring approaching, the board recognized the need for outdoor sports activities during the summer months for its male members and in May 1937, association football and handball was added to the club's repertoire. In the first season, one men's association football team was created. In 1940, Ullerød GF moved in to their first club house located at Frejasvej, containing a small meeting room on the ground floor and a changing room on the first floor, next to an association football field, that was also used for (outdoor) handball. Athletics became part of the sports club in 1938 or 1939. As a consequence of the new sport activities being included, a reorganisation was decided by the board in 1941, that created five independent sports departments (for athletics, gymnastics for women, gymnastics for men, handball and association football) and one unifying main organisation. At the 25 years anniversary, the club had approximately 800 members, where 500 members were attached to the gymnastics department, which at the time was one of Zealand's largest departments membership wise.

During the early mid 1960s, the local politicians at the city and parish councils expressed their wishes for a merger between Ullerød GF and Frederiksborg IF in connection with the upcoming merger in 1966 between the local municipalities; the central Hillerød Købstadskommune and the surrounding Frederiksborg Slotssogns Kommune and Nørre Herlev Kommune, but the proposal for the club merger was eventually rejected with a large majority by the board and members.

Up until the 1960s, the then small football department did not draw great attention to itself, playing in the lower ranking regional leagues, primarily the SBU's A-række, with players such as Edvin Nilsson, Svend A. Nielsen og Charly Hansen as the most prominent names in the club's first thirty years. In the 1966/67-season of the Danish Cup, the club reached the first proper round under the Danish FA for the first time, where it was defeated 4–0 by Kastrup BK, while reaching the SBU's Serie 1 in 1967 following two consecutive promotions.

The club was renamed Hillerød Gymnastik- og Idrætsforening (abbreviated HGI) in the spring of 1968 after the debate regarding a name change had been initiated in 1962. A reference to only one of several sports was kept in the name to signify the importance of the gymnastics department and its strong foundation within the club. The need for a name change was in part justified by a judgment from the Zealand FA, that ruled in favour of the away team, Køge, whose players were not able to find the playing ground for Ullerød GF during a league match in the 1960s, thinking that the home team were playing their matches in the district of Ullerød.

The club's first real club house was inaugurated in October 1968 at Selskov Stadium, funded partly by grants from Frederiksborg Slotssogn (on the condition that the work would be done by volunteers) and following a two year long construction period, that was started in 1966, and which underway was affected by a storm in February 1967. After the sport club introduced a women's football department in 1970, the men's association football department started being referred as Hillerød GI Herrefodbold, while the women's department was referred to as Hillerød GI Damefodbold. At the club's 40 years anniversary in 1977, the number of memberships were grown to approximately 2,100, with 1,000 members attached to the gymnastics department. The football department introduced the youth tournament, Copenhagen Tivoli Cup, in 1991. In the spring of 2000, the club house at Hillerød Stadium burnt down and a new club house was not built until some years later, featuring several more changing rooms and a weight training center.

In the 1970s, Hillerød G&IF surpassed the local rivals, Frederiksborg IF as the leading club in Hillerød. While Frederiksborg IF was regarded as the city's old renowned upper class sports club, both the sports management and the active athletes at Ullerød GF/Hillerød G&IF viewed themselves as being a working class club — which in practice was embodied by the local politicians and business community being more responsive and supportive towards Frederiksborg IF. Hillerød G&IF's senior men's team won their regional Series 1 league group in the 1976-season, including winning the Zealand Series 1 League Championship the same year, securing a promotion to the Zealand Series in the upcoming 1977-season for the first time in the club's history under the guidance of playing head coach Finn Wiberg. The team managed to compete in the top regional league for three years until a relegation in the 1979-season sent them back to the second highest league level on Zealand. Wiberg left the club after the 1979-season, but returned for a second round at the club in 1983, managing to secure the club's return to the Zealand Series for a second time.

Initially, Hillerød Fodbold was started in January 2007 as a youth cooperation between four clubs; Hillerød GI, KBK Hillerød, Gadevang and Ålholm IF. Beginning from 1 July 2009 the senior men's football team of Hillerød G&IF were now renamed Hillerød Fodbold. At the end of the 2009/10-season, the entire senior team consisted of homegrown club players.

A completely new team with a low average age was put together for the 2011/12-season, consisting of six U19-players and 22 years old team captain. In November 2015 the youth and reserve men's teams of Hillerød G&IF were also renamed and changed their shirt colours from blue/yellow to orange/black.
