The Saturation Cup is a six-hour motorcycle endurance race held at the Mac Track and features a classic Le Mans–style start. Designed as an endurance challenge rather than a sprint, the event emphasizes strategy, consistency, and teamwork. The name “Saturation Cup” reflects the spirit of the race: competitors embrace wet conditions, with rain not only expected but welcomed as part of the challenge.
