The 2025 Ca Mau Marathon is an activity within the "Ca Mau - Destination 2025" program, accompanying the 2nd Ca Mau Crab Festival in 2025. The event was organized by the Department of Culture, Sports and Tourism of Ca Mau province in coordination with Vietrace365 Joint Stock Company, aiming to promote the mass sports movement, while promoting the local image.
According to the plan, the tournament will take place on November 15 and 16, 2025, starting at Hung Vuong Square, Bac Lieu Ward (Ca Mau Province).
