Crossword Genius

Increase in cost of healthy exercise (4)

Ross

I believe the answer is:

hike

I believe this is a double definition.

'increase in cost' is the first definition.
(I've seen this in another clue)

'healthy exercise' is the second definition.
(hiking is a form of exercise)

'of' is the link.

(Other definitions for hike that I've seen before include "Travel by Shank's Mare" , "physical exercise" , "Long walk; big price rise" , "Long, hard walk" , "Long march; increase" .)

I've seen this clue in The Times.
