Dressed to ride around after a race (7)
I believe the answer is:
attired
'dressed' is the definition.
(attiring is a kind of dressing)
'ride around after a race' is the wordplay.
'around' indicates an anagram.
'after' says to put letters next to each other.
'race' becomes 'tt' (**).
'ride' anagrammed gives 'ired'.
'a'+'tt'='att'
'ired' after 'att' is 'ATTIRED'.
'to' is the link.
(Other definitions for attired that I've seen before include "Turned out" , "got up" , "Dressed or clothed" , "surrounded by duds" , "Wearing clothes" .)
