To combat heat stress disparities, Athletics Kenya launched Hydration Equity Zones at all national races from May 1, 2025—placing extra water, shade, and misting fans in high-sun sectors (e.g., final 2km of marathons), where low-income and female runners often cluster. Equity isn’t kindness—it’s design, said AK Medical Director Dr. Lucy Waweru. At the Nairobi Marathon, heat-related incidents dropped 63% in targeted zones. World Athletics featured the model in its *Heat Safety Guidelines*. All race directors must now submit equity maps for approval.
