The 2026 Can Tho Heritage International Marathon is scheduled for December 19–20 at Song Hau Park, with the main race day on December 20. Organisers have introduced the 5 km Conservation Vietnam distance to connect running with wildlife and nature conservation. The accessible route is intended for beginners, younger participants and families. The stated scale of more than 10,000 participants is an expectation for the forthcoming event, rather than a completed attendance count.
