For those who want to travel to Produttur, Andhra Pradesh from Bangalore, in the early morning, there are buses available between 5:00 AM and 6:00 AM. In the one hour, 2-3 buses of APSRTC(one direct and others are till Kadapa) and 1 bus of KSRTC till Kadapa. From Kadapa, there are plenty of buses to Produttur and the expected journey time is 60-90mins.
Recently, I had to travel to Produttur to attend one family function. I decided to travel by car. But last minute, I decided to travel by bus. I boarded KSRTC bus at 6:00 AM that goes till Kadapa. Conductor promised me to reach by 11:30 AM. And, the driver did it!!! :-) I got surprised. Usually, day-time buses have few passengers and the buses are expected to be stopped in any possible places on the way.
Total distance from Bangalore to Kadapa is ~250kms (Map). Till Chintamani, the ride was very slow and stopped for breakfast for ~20mins. After that, bus picked the speed and crossed every possible bus on the road on that day. May be something was to do with the breakfast :-). I reached Kadapa sharp 11:30AM. I boarded Produttur bus from there and reached around 1:00PM. What a ride!!!
