Sprinting contest I’m beginning to explore (8)

I believe the answer is:

eventime

I'm a little stuck... Click here to teach me more about this clue!

'sprinting' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.

'contest i'm beginning to explore' is the wordplay.
'contest' becomes 'event' (I've seen this before).
'beginning to' indicates taking the first letters.
The first letter of 'explore' is 'e'.
'event'+'im'+'e'='EVENTIME'

Can you help me to learn more?

I've seen this clue in The Hindu.
