Speed runs up getting run over (5)
I believe the answer is:
Here is my best explanation:
'run over' is the definition.
'speed runs up' is the subsidiary indication.
'speed' becomes 'pace' (pace is a kind of speed).
'runs' becomes 'r' (cricket abbreviation).
'up' says the letters should be written in reverse (in down clue: letters go upwards).
'pacer' in reverse letter order is 'recap'.
'getting' is the link.
(Other definitions for recap that I've seen before include "Sum up what has been said", "Final summary", "Go over things again", "Say again", "Caper (anag)", "Restate", "Go over again in the mind", "Summarising statement", "Sum up (abbrev.)" and "Run through again (Inf)".)
