More than one stretch breaks back (5)

I believe the answer is:

spans

'more than one stretch' is the definition.
(I've seen this in another clue)

'breaks back' is the wordplay.
'breaks' becomes 'snaps' (snapping is a kind of breaking).
'back' shows that the letters should be reversed in order.
'snaps' in reverse letter order is 'SPANS'.

I've seen this clue in The Telegraph.
