The Niagara Falls International Marathon celebrated its inaugural running in 1974. The race was known as the Skylon Marathon. Beginning during the first wave of the North American running boom, it quickly became a favourite as it was, and still is, the only marathon in the world that starts in one country and finishes in another… a destination marathon that crosses an international border, providing the runners with an experience of a lifetime. Niagara Falls International Marathon is also a Boston Qualifier.
