The fast-food brand, which already sponsors the New York marathon, recently trialled a 5km run in Northern Ireland.
The Subway Love Your Heart Family 5K run took place on 30 September and included a partnership between Subway and Heart Research UK.
Subway plans to continue the partnership with the charity for the forthcoming races too, which will include half and full marathons. Money raised will go toward Heart Research UK and the Subway Healthy Heart grant scheme, which supports communities to help them lead healthier lifestyles.
