The club was founded in 1910 with the basketball section beginning in 1947 and the first local Ain department championship coming in 1956. Bourg jumped to what is now the fifth division in 1963 and earned promotion in 1969. The club began producing better young French talent such as Jean-Luc Roediger and Thierry Maitejean, and the first American players came to the club in 1973. Bourg was relegated back to the fifth division in 1974 but returned to the fourth level just one season later. The club dropped back to the fifth division in 1978 and even spent one season in the sixth division. Bourg moved from the fifth to fourth league in 1985 and made a big jump in 1994 by winning the fourth division title with top names such as Jerome Monnet and 21-year-old captain Jean-Luc Tissot. In just its second season in the third flight, Bourg captured the title and entered the world of professional basketball by reaching the second division in 1996 - thanks to the one-year stint of future French international and Olympic silver medallist Crawford Palmer. The club reached the elite level in 2000 by winning the second division title. Bourg stayed in the first division for seven seasons - the biggest highlight being reaching the French Leaders Cup final in 2006. Bourg dropped to the second division in 2007 and stayed there for seven more seasons before earning promotion back to the top flight in 2014. It was a just a one-year stay though as the team went back down to the ProB. The club did have success after the relegation, winning the French ProB Leaders Cup crown in 2016 and taking the French second league title in 2017. Bourg showed right away back in the first division that it was ready to challenge for the playoffs. The team missed the post-season by one game in 2018 and Bourg had the same record as the last playoffs team in 2019, finishing ninth for a second straight season. Bourg also reached the 2019 French Leaders Cup final, losing to Strasbourg. In 2019-20, Bourg was on its way to finally reaching the playoffs with a 16-9 record and fifth place in the standings when the Covid-19 pandemic caused the end of the season. Bourg now gets the chance to show what it can do on the European stage.
