It would be great to see how the Delhiites respond to the Airtel Delhi Half Marathon, a mass participation long distance running event. With the word spreading as to many stars also making extra effort to train for the event and run for a good cause, the event could be a huge success. Nearly 30,000 are set to take over the streets of Delhi for about four hours on November 1. The star list includes Purab Kohli, Rahul Bose etc.
