If you can run a marathon in Delhi you can run anywhere, the Delhi High Court today said while referring to the "hazardous" air pollution levels here and suggested measures like immediate extinguishing of landfill fires and ensuring only CNG taxis enter the national capital to improve air quality.

"If anyone can run a marathon in Delhi, they can run anywhere," a bench of justices BD Ahmed and Jayant Nath said after it was informed that despite the high pollution levels there was going to be a marathon in the city on November 20.

The court, however, asked the Delhi government to issue an advisory for the public informing them about the air quality which the bench noted contained pollutants four times more than the prescribed standard.
