In 2024, the Calgary Marathon celebrated its 60th "Diamond" Anniversary with a one-time 60 km ultramarathon road race and finisher medals that featured two "diamonds". In 2024 the marathon handed out non-alcoholic beer at aid stations, becoming the first marathon in North America to offer non-alcoholic beer at an official aid station along the course.
