Start Marina Bay Sands, run waterfront promenade toward Gardens by the Bay, loop via Helix Bridge, return along Esplanade. Perfect 5km with stunning reflections in calm morning water.

Best 6-7am when light is golden and tourists haven't arrived. Well-lit safe path, water fountains every kilometre. Finish with coffee at Ya Kun in Marina Bay Financial Centre.

Weekend mornings sometimes have informal running groups welcoming visitors.
