Starts to take rugby's easy kicks and some hard trips (5)

'hard trips' is the definition.
'treks' can be an answer for 'trips' (trek is a kind of trip). I'm not sure about the 'hard' bit.

'starts to take rugby's easy kicks and some' is the wordplay.
'starts to' says to take the initial letters.
'and' says to put letters next to each other.
'some' becomes 's' (this might be a standard abbreviation I've not previously seen).
The first letters of 'take rugby easy kicks' is 'trek'.
'trek'+'s'='TREKS'
