Bangalore to Goa is 560km. Taking Tumakuru route via Belgaum you could reach Goa. Better to halt in Goa and plan sightseeing based on your travel plans. From Goa travelling to pune then to Shirdi you could take second break. Either you halt in Pune or in Shirdi. From Shirdi reaching chittorgarh is 12 hours drive. Better to halt for a day Then travel on Delhi highway. It takes 5 to 6 days to reach Delhi by road from Bangalore. If you are planning to visit spots inbetween then you need some more days extra based on your travel timings. Once I did road trip from Bangalore to Goa and then to Pune. We halted and reached Pune on third day.
