Where rivers run very fast (6)

I believe the answer is:

rapids

(Other definitions for rapids that I've seen before include "Fast-flowing and turbulent part of a river" , "what intrepid canoeist enjoys" , "White water area" , "Part of a river where the current is very fast" , "Fast-flowing river section" .)

I've seen this clue in The Irish Times.
