Known for its lively Oktoberfest theme, participants don feathered hats and lederhosen while enjoying Bavarian music, sausages, and sauerkraut along the course. The 10 km event also serves as the Québec 10 km Championship, and the venue hosts the sixth stage of the Coupe Québec Viens Courir series. Services include official chip timing, cadence pacers, aid stations with BRIX electrolytes every ~3 km, high-quality tech shirts and finisher medals (plus medal engraving by Sun Life), and festive post-race entertainment.
