Way to travel shows pace (6)
I believe the answer is:
stride
'pace' is the definition.
(I know that pace can be written as stride)
'way to travel' is the wordplay.
'way' becomes 'st' (abbreviation for street).
'to travel' becomes 'ride' (eg to ride a bus).
'st'+'ride'='STRIDE'
'shows' acts as a link.
(Other definitions for stride that I've seen before include "Walk along in direst way" , "Long step of direst kind" , "Take long paces" , "Walk with long steps" , "Move with long steps" .)
