Run to see odd pies (4)
I believe the answer is:
lope
'run' is the definition.
(I know this)
'see odd pies' is the wordplay.
'see' becomes 'lo' ('lo' is an archaic exclamation meaning 'look!').
'odd' means one should take alternating letters.
The alternating letters of 'pies' are 'pe'.
'lo'+'pe'='LOPE'
'to' is the link.
(Other definitions for lope that I've seen before include "Run with long strides using pole" , "Take long, bouncy strides" , "Run with long steps carrying pole" , "Run along easily" , "run gently" .)
