Coastal Ultra Bangladesh (CUB) is an inspiring non-profit initiative that organizes ultra-marathons and endurance challenges across Bangladesh—from the coast to the capital—to promote eco-tourism, environmental awareness, sustainable development, community wellbeing, and the blue economy. By organizing events such as the Coastal Ultra along Marine Drive in Cox’s Bazar and the Dhaka Stadium Run at the National Stadium in Dhaka, CUB aims to showcase the country’s natural beauty and heritage, raise environmental awareness, and brand Bangladesh globally as a destination for adventure and responsible tourism.

Beyond sports, CUB is deeply committed to charitable and social initiatives that empower underprivileged communities. Two notable charity partners of Coastal Ultra Bangladesh are Pawmang Primary School in Bandarban, which provides education and shelter to hill children, and Half Mad Human, a volunteer group supporting neglected and blind children, impoverished families, and the elderly. Through such initiatives, CUB combines sports, social welfare, and environmental awareness to build a more inclusive and sustainable Bangladesh.
