One with anecdotes and race to run in medley? (9)
I believe the answer is:
raconteur
'one with anecdotes' is the definition.
(a raconteur tells stories)
'race to run in medley?' is the wordplay.
'in medley?' is an anagram indicator (I've seen 'in medley' mean this (I've seen this in other clues)).
'race'+'to'+'run'='racetorun'
'racetorun' is an anagram of 'RACONTEUR'.
'and' is the link.
(Other definitions for raconteur that I've seen before include "He tells a story well" , "Teller of anecdote" , "A good teller of tales" , "anecdotalist" , "One relates" .)
