Welcome to the CCMI Reef Relief Squad for the 2025 Walkers Cayman Islands Marathon! 

CCMI is a marine research and education organisation located in Little Cayman on one of the most biodiverse ecosystems in the region. We are working to understand how we can protect coral reef ecosystems for the future.

Rapidly changing climate is causing significant pressure on coral reefs, threatening their very survival. We are at a point in time where coral reefs urgently need our help. 

CCMI is at the forefront of understanding and addressing coral decline—including the effects of heat stress and disease—and have become regional leaders in the study of mesophotic reefs (30–150 m deep), an area of science with significant potential for uncovering climate refuges. We pair this research with immersive education and outreach activities, both in Little Cayman and around the world.

When you raise money through the Reef Relief Squad, you are helping sustain the timely, critical work CCMI is doing for the future of coral reefs!
