Skater forced to move very fast (6)
I believe the answer is:
streak
'move very fast' is the definition.
(I've seen this before)
'skater forced' is the wordplay.
'forced' is an anagram indicator.
'skater' with letters rearranged gives 'STREAK'.
'to' is the link.
(Other definitions for streak that I've seen before include "run? Barely!" , "'Sudden flash, of lightning say (6)'" , "Spell (of good luck)" , "Appear in the nude" , "Lucky spell" .)
