Hoërskool Bellville annually participates in the MTBS athletics competition, along with three other schools from the Bellville area: D.F. Malan, Tygerberg and Stellenberg. MTBS is especially well known for the performance of these schools' non-participating pupils on the pavilion as they perform songs and cheers to encourage their athletes during the day - for which a trophy is also awarded. Bellville has won this singing section in 2003, 2004, 2006, 2008 and 2019.
