I believe the answer is:

dashes

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

'runs' is the definition.
(I know this)

'cricket trophy presented after 500' is the wordplay.
I cannot really understand how this works, but
'trophy' could be 'ashes' (I've seen this before) and 'ashes' is found within the answer.
'500' could be 'd' (Roman numeral for 500) and 'd' is found within the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?

(Other definitions for dashes that I've seen before include "Runs fast with shades" , "Long signals in Morse code" , "Strokes" , "hares" , "Quick run or sudden rush" .)
