Hence, Utah runs these now and then (4)
I believe the answer is:
thus
'hence' is the definition.
(synonyms)
'utah runs these now and then' is the wordplay.
'these now and then' indicates alternate letters (letters taken on a regular basis, now and then).
'utah'+'runs'='utahruns'
The alternating letters of 'utahruns' are 'THUS'.
(Other definitions for thus that I've seen before include "In this manner" , "Therefore, hence" , "In this way" , "an original Christmas gift" , "It follows" .)
