New Delhi: Former India Test captain Rohit Sharma opened up about his recently concluded Test career and said that the format was both challenging and draining but he managed its demands by focusing on preparation. The 38-year-old who scored 4301 runs at an average of 40.58 in 67 Tests retired from the long format in May a year after stepping away from T20I having led India to a World Cup title in the format. On Monday during a CEAT event he looked back on his career while discussing preparations for high-pressure moments in a panel discussion. Rohit Sharma opens up on how challenging Test cricket is It is something that you prepare for because the game demands longevity he said. Especially in the Test format you have to last for five days. Mentally it is very challenging and it is draining as well. But all cricketers have been brought up playing First-Class cricket. When we start playing cricket at a competitive level even in Mumbai club cricket (matches) go on for two days (or) three days so we are built like that and it starts at a very young age for us. It kind of makes it a little easier how to respond to situations that are there in front of you he added. Rohit also focused on the importance of thorough preparation Rohit mentioned that not all young players understand the importance of thorough preparation early in their careers but they come to understand its value over time. ...when I started playing the sport it was all about having fun enjoying (it) Rohit said As you go on you start playing age group cricket and you kind of keep moving forward from that. Slowly as you meet a lot of senior players (and) coaches they talk about how important it is to prepare well. When you are very young you dont understand the importance of preparation. But as you go along you understand it gives you a kind of discipline that the game asks for so it starts with preparation understanding what exactly you need to do he said. Rohit mentioned that staying mentally fresh is a key to be a top performer  Rohit stated that maintaining momentum for top performance particularly in Test cricket starts with staying mentally refreshed. It takes a lot when youre playing the longest format and concentration is something that is the key because you are speaking about high level performance and when you are expecting to put in high level performance it starts with being mentally fresh all the time he said. A lot of work starts behind the scenes. Like I said in preparation. I have to go back again to that because that is where it all starts. You prepare yourself to sustain for the longer period of time on the field. Rohit mentioned that his experience was no different and gradually he started dedicating a significant amount of time to preparations. It exactly happened to the same (way) with me when I started playing for Mumbai and then went on to play for India. A lot of the focus a lot of my time was given (on) how I prepped before the game he said. Because once the game starts its all about reaction and you react to whatever is thrown at you whether it is a pressure situation whether it is making the right decision on the field with the bat or with the ball. A lot of time was devoted to prep and Im sure its not just in cricket but anywhere whatever you do with life I think preparation is the key he added.
