Watch the
movement begin.

One decision to move can inspire a family, a workplace and a nation.

The movement

A healthier
India begins
with one
person
deciding to
move - you.

100 Days of RunningPromoted by Procam

To the 80,000+ people who have moved with HDOR before: come back, and bring someone with you. And to the 1.8 million+ runners in the Procam community: invite your family, friends and colleagues to take the first step.

One person becomes a family, families become communities, and together we can build a healthier you - and a healthier India, a healthier Bharat.
