Ajay, a professional Basket Ball Player whose sporting career was cut short because of injuries. An MBA from a top ranking Business School he gave up a promising corporate career to start into fitness.
“Having suffered numerous injuries I wanted to provide safe and effective exercise options that can engage a person into a lifetime quest of self improvement. Competitive sports are too demanding and have a short life span. I was looking for a sport where everyone wins and running became a natural choice.” says Ajay.
With a background in Team Sports, Ajay promoted running as a community sport and not as an individual sport. When Ajay read about Raramurian philosophy and culture, it also echoed with his sentiments and he felt rightly aligned, bringing Chambal Challenge to fruition as a result.

In a true Raramurian fashion Avinash has nurtured the running community, like a family. Making sure that values of co-operation, camaraderie and brotherhood, permeate evenly.
A true believer in learning by doing, Avinash has very gradually shaped himself into an ultra marathoner. Starting from regularly and consistently bettering his own performance at some of the best marathoning events in India (PB: 4Hour48minutes at Tata Mumbai Marathon), he recently made a nose dive into ultra distance running by completing few Ultra-Marathon Including 80k TUFFMAN at Jaisalmer & 24Hour Stadium Run (covering 127KM) at Chandigarh.
At Chambal Challenge, Avinash not only brings his enthusiasm in putting together a great race, but also hundreds of miles of running experience in observing and creating world class races.
