3. Chalk
Chalk! Everybody’s favourite thing to throw around and look like Lebron James with. In all seriousness this stuff takes away all moisture from the surfaces it touches and as a result gives a grippy feeling. Chalk is important for every throwing event and especially when there is rain about. Throwing in the rain without chalk will significantly impact your chances of throwing well.
Generally meets should have chalk available for athletes but if your event is near the end of the day and numerous throwing events have occurred beforehand, the ‘chalk bucket’ can be running on empty. So by bringing chalk you are prepared to throw your best!
