Developing a routine before a competition block increases your likelihood of perform well by controlling certain variables to get you into your best mindset.
A pre-competition routine includes elements such as how much rest you get the night before and what you eat before you bowl, and digs into details like when you put your shoes on prior to practice and what music you listen to. All of these can affect your readiness to perform to your potential.
Think back on good performances and consider your personality to develop a pre-competition plan, from the night before the event all the way up to the first ball of practice.
