The Zero Loop Ultra Marathon

3rd Edition



“I don’t know where you are but if you are a runner I know we are destined to meet, no matter the distance between us. For when I look in your direction I see a reflection of my soul staring back at me.”

Ajay Singh Sethi

Founder IRC & Race Director Chambal Challenge

Is it for me?

“Every morning in Africa, a gazelle wakes up, it knows it must outrun the fastest lion or it will be killed. Every morning in Africa, a lion wakes up. It knows it must run faster than the slowest gazelle, or it will starve. It doesn’t matter whether you’re the lion or a gazelle-when the sun comes up, you’d better be running.”

-Christopher McDougall

Chambal Challenge: The Kumbh of Ultimate Runners

Each Ultra Marathon claims to be the toughest. And each is, in its own way. Chambal Challenge is different and probably the only Ultra Marathon in the country where the challenge is not just the distance but the rugged terrain and distinct topography. This Ultra combines road run, uphill, downhill and trail running into one long run where every few kilometers changes in the terrain and the landscape requires the best from a runner in terms of strategy as well as skill. Certainly not for those who are looking for a personal best at a given distance.

Chambal Challenge is a Zero Loop Ultra Marathon that tempts as well as tests a runner. It provides runners with an opportunity to grow from a half marathon to a 33K, from a full marathon to an ultra-marathon 50K or 63K or 84K. It dares you to ‘go beyond’, to open yourself to ‘the unknown’, knowing fully that its facing the unknown, the uncertain, the untried that defines us and brings forth powers that can transform an ordinary human being into an extraordinary one.


The Tarahumara (a tribe that lives in north western Mexico) called themselves ‘Raramuri’, means “runners on foot” or “the light footed one”. With widely dispersed settlements, these people developed a tradition of long-distance running up to 200 miles (320 km) in one session, over a period of two days through their homeland of rough canyon country, for inter-village communication, transportation, and hunting.

There are Raramuris who can still run 400+ km in a single session. Chambal Challenge gives an individual a chance to explore and get in touch with a Raramuri that exists within each one of us.

A fantastic Ultra Marathon which has not only been planned in an excellent manner but executed extremely professionally. Every small facet of a runner participating in the Ultra Marathon was taken care of by the organizers. The route was extremely challenging & the high point was the post run Lunch n evening Extravaganza which I have not seen anywhere else. Overall an outstanding Ultra Marathon. Strongly Recommend Col.

It was such an exhilarating experience at the Chambal Challenge with impeccable hospitality and a fantabulous organization of the event. The organizers moved heaven and earth to completely pamper the athletes with sumptuous food and homely stay. To add to this was the scenic course of the running course with fresh air which we definitely miss in the metropolitan cities. The running course, no matter, with howsoever many adversities was studded with natural beauty and helpers and volunteers to assist the runners as and when required. Thumbs up to the event and organizers. A highly recommended event for all the runners to have an experience of a lifetime!!!

The route was scenic and beautiful. Constantly changing landscape and the beauty of the course kept me going and challenge got the best out of me. While Chambal Challenge 2018 was a life time experience I am looking forward to better my performance in 2019.

Deepa Yadav


One of the neatest race executions I have witnessed. From registrations, to the awards gala, Chambal 2018 was a treat, with perfection perfected and keen attention to detail. Looking forward to an epic race in 2019!

Narendra Awasthi


This course helped me push my personal limits and get to the next level. Absorbing in the beauty of Chambal’s astounding wilderness and the support of an expert crew made Chambal Challenge one of the most memorable running experiences I have ever had.

MS Chauhan


A very scenic route, serene and peaceful away from the noise of the city. it's almost like meditation. The view of the cleanest river of India Chambal takes away any tiredness that one.might feel along the way. The view point at the finish makes you feel on top of the world. The support team is outstanding always ready to give you a hand. I say,if you are a runner and haven't run the Chambal Challenge then you are missing something. the route and the camaraderie I felt with co runners lingers on in my mind long after the run ends.

Nidhi Kasaliwal


Having run the Comrades Marathon this year, I can assert with confidence that Chambal Challenge is as close as it can get to having an international racing experience on home ground.

Nitin Saini


Chambal Challenge ’18 prepared me up to one of the most difficult races of my career – La Ultra 111.

Gagan Deep Meena -Looking forward to the good vibes at CC’19.
