First-time marathon runners can reduce aortic stiffness by a vascular age of up to four years, even if they take on the challenge later in life, UK researchers show.

A study on the London Marathon found the biggest gains were in slower, older men who also had relatively high blood pressure when training began, though the researchers said it was not clear why they benefitted most.
