Mix the way I start running (4)
I believe the answer is:
stir
'mix' is the definition.
(I've seen this before)
'way i start running' is the wordplay.
'way' becomes 'st' (abbreviation for street).
'start' suggests taking the first letters.
The initial letter of 'running' is 'r'.
'st'+'i'+'r'='STIR'
'the' acts as a link.
(Other definitions for stir that I've seen before include "Stimulate; prison" , "Start to move" , "in which you'll find people with convictions" , "Commotion to mix" , "Kerfuffle" .)
