Hey Raghav, Yesss it's feasible ... but if at all you are used to all day ride .. then it's feasible ... As far as road conditions is concerned almost entire stretch is good ... apart from a little stretch in North Karnataka ... Happy and safe Travelling Bro!!!
Hi Raghav, I have covered this route before, and i will suggest you not to plan in a day. No doubts Roads are in very good condition but it is a very long route(more than 1300km) hence i recommend you to break your journey somewhere in North Karnataka (Dharwad / Dandeli are good option). If you time i would say make it 3 day drive and cover some amazing drive routes on your way to Mumbai.
HI Raghav, the distance between Chennai and Mumbai by road is 1330 Km and even if you maintain an average speed of 60-70 km/hr it would still take you 20-22 hours to cover this distance and it would be a bit too much to ask from yourself. I don't think you should try to in a single day and break the journey is two parts.
