Unin ministers Harsh Vardhan and Mahesh Sharma will flag-off the marathon from India Gate on October 15, coinciding with the birth anniversary of former president Dr A P J Abdul Kalam, according to an official statement.
"The campaign is being launched to create a mass movement for reducing air pollution. The idea behind the campaign is to entrust a sense of responsibility among people, so as to consider clean air as a collective responsibility.
"In order to achieve the objective of 'Clean India' in a true sense, clean and pollution-free air needs to be a priority," the statement said.
"Air pollution is one of the pressing environmental challenges being faced at present. With the onset of winters, increased emissions from various existing sources and burning of crop residues, coincides with adverse meteorological conditions," the statement said.
"The month of October 2017 is also important, as India is hosting the FIFA U-17 World Cup. The government has been taking various steps to address the issue," it added.
