HDOR

The HDOR app is a fitness program that encourages users to engage in regular physical activity through running, walking, or cycling. Launched in 2015, HDOR is a global challenge that aims to help people develop a habit of staying active and making exercise a part of their daily routine. The app is built around the principles of consistency, discipline, and community, with users committing to stay active for 100 days. This edition of HDOR is expected to attract over 50,000 participants from India and around the world, making it one of the largest multi-day fitness challenges. By joining the HDOR community, users can track their progress, stay motivated, and celebrate their achievements with others who share similar goals.

100 Days of Running (HDOR) is a global fitness movement started in 2015 with a simple goal - to help people make running and physical activity a part of their everyday lives.

The challenge is built around consistency, discipline and community. For 100 days, participants commit to staying active, building healthier habits and pushing themselves a little further each day.

The 2026 edition begins on 10 October 2026 and is expected to bring together more than 50,000 participants from India and around the world, making HDOR one of the largest multi-day fitness challenges of its kind.

HDOR is not about being the fastest runner. It is about showing up, staying committed and making movement a habit - whether you are taking your first steps towards fitness or already an experienced runner.

Track your journey, stay motivated, participate in challenges, celebrate milestones and be part of a growing community that believes every goal is achievable with consistency.

Mumkin Hai. Come What May.
