Runner bumping into rival — what could be more annoying? (7)
I believe the answer is:
'more annoying?' is the definition.
('pesky' can be a synonym of 'annoying')
'runner bumping into rival' is the wordplay.
'runner' becomes 'ski' (ski is a kind of runner).
'bumping into' indicates putting letters inside.
'rival' becomes 'peer'.
'ski' going within 'peer' is 'PESKIER'.
'what could be' acts as a link.
