On a sunny but somewhat foggy morning, a group of Lycra-clad runners stretch their hamstrings in Delhi's Nehru Park. Sporting yoga mats, water bottles, breathing masks and heartbeat monitors, the group is meeting for their weekly training for the Airtel Delhi Half Marathon.
Now, they don't know for sure whether the event will be held at all.
The Indian Medical Association (IMA) has asked the organisers to cancel the marathon to be held on November 19 at 7 am amid rising level of air pollution in the national capital. Health experts are saying that bad air quality can aggravate existing lung diseases and asthma.
"High PM2.5 levels can increase blood pressure and increase the risk of acute cardiovascular events such as heart attack and stroke. Hence, we demand that the event be cancelled immediately and be organised at a later date when air quality gets better," the IMA said in a statement.
The organisers say they will deploy nebulisers along the marathon's routes to help people if they developed abnormal breathing pattern along with ambulances carrying oxygen tanks. A nebuliser device changes liquid medicine into a fine mist so that the patient can breathe in the mist easily.
Reeti Sahai, a resident of Delhi, has run seven editions of the Airtel Delhi Half Marathon and is training for the eighth one. "Just like me, many more have been training for months now and there'll be participants from Ethiopia, Kenya and many Indian states. They should have thought about cancellation earlier, not at the last minute," she says.
The IMA is not impressed. The association's national president Dr KK Aggarwal says the organisers want to proceed with the marathon despite knowing the risks. "Will Airtel be responsible if someone becomes really sick during the run? We will speak with the chief minister and take it up with the Chief Justice," he said.
