Race organisers declared the event an unequivocal success that “lived up to its legacy of being the world’s most prestigious half marathon”. Doctors warn running in severe pollution can trigger asthma attacks, worsen lung conditions and increase the risk of heart attacks and strokes. The Indian Medical Association had asked the Delhi High Court to postpone the event, but were told organisers had taken proper precautions. But as the race progressed pollution readings climbed above 200 - levels at which active people “should avoid all outdoor exertion”, the US embassy warns. Delhi is often ranked one of the world’s most polluted capitals, and local authorities have been blasted for failing to offset this annual scourge.
