Max Bupa Walk for Health is a first of its kind initiative which aims to encourage people to walk more.
The five kilometre walk in Delhi was flagged off by Sania. The Mumbai walk was flagged off by leading Bollywood actor Sonam Kapoor.
Expressing her belief in the initiative, Sania said, "More and more people are realising the importance of being fit and healthy."
"I personally believe that walking is a great way to stay fit and I encourage everyone to start walking as it is the easiest and the best way to get healthier."
Celebrities like Manish Paul, Pooja Bedi, Kunal Kohli, Dilip Tahil, Raza Murad, Meiyang Chang and Smriti Irani also participated in Mumbai.
This year the initiative focused on Delhi and Mumbai, as owing to a sedentary lifestyle, people living in these metropolises are more prone to stress and lead an unhealthy life.
