About Duathlon

Chennai Duathlon is one
of Chennai’s most exciting endurance sporting events, bringing together
runners, cyclists, fitness enthusiasts, and athletes from across the city and
beyond. What began as a passion for creating a challenging yet enjoyable
multisport experience has grown into an event that celebrates fitness,
determination, community, and the spirit of competition.

Whether you are an experienced endurance athlete looking to push your limits or participating in a duathlon for the very first time, Chennai Duathlon is designed to give every participant an unforgettable race-day experience.

Run. Ride. Run.

The Chennai Duathlon combines two of the most loved endurance disciplines - running and cycling - into one challenging race. Participants will take on a run-bike-run format that tests their endurance, strength, speed, and ability to keep pushing forward.

This year, participants can choose the category that best matches their experience and fitness level:

Sprint Category

5 KM Run → 20 KM Cycling → 2.5 KM Run

Perfect for first-time participants and those looking to take on their first
duathlon challenge.

Classic Category

10 KM Run → 40 KM Cycling → 5 KM Run

Designed for experienced athletes who are ready to take their endurance to the
next level. More Than Just a Race, Chennai Duathlon is not just about crossing the finish line. It is about the journey - the early-morning training, the excitement at the starting line, the energy of riding alongside fellow participants, and the satisfaction of completing something you once thought was difficult.

With a carefully planned race route, a supportive race environment, refreshments, entertainment, and a community of like-minded fitness enthusiasts, Chennai
Duathlon brings the spirit of endurance sport to Chennai. Built for Every Level

You don't have to be a professional athlete to participate. Whether you're chasing a personal best, preparing for your next endurance challenge,
getting back into fitness, or simply looking for a new experience, Chennai
Duathlon gives you the opportunity to challenge yourself at your own pace.

Come as a first-timer. Race like an athlete. Finish like a champion.

Run. Ride. Run.

About Mongrels

Mongrels is a Chennai-based cycling club built around the love of cycling, friendship, adventure, and an active lifestyle. Founded in 2010, what started as a group of cycling enthusiasts has grown into a close-knit community of riders who believe cycling is about much more than just the bike.

We ride together three times a week, exploring Chennai, challenging ourselves, and enjoying the simple pleasure of riding with good company. From early-morning rides to casual hangouts after a ride, Mongrels is as much about the people and friendships as it is about cycling.

But the journey doesn't stop at Chennai. Every year, we take our passion for cycling beyond the city with an international cycling outing, creating opportunities to explore new places, experience different roads, and make memories together.

Over the years, Mongrels has continued to bring together cyclists of different ages, backgrounds, and experience levels - from passionate riders to those simply looking to enjoy the ride.

Ride together. Explore together. Grow together.

And with the Chennai Duathlon, Mongrels brings that same spirit of community, challenge, and adventure to the world of multisport.

Mongrels - Cycling. Friendship. Adventure. Since 2010.
