Exact route changes of course with the river conditions, but the general idea is take the shortest route point to point crossing the main stream with care as required. There is a wet weather track/route on the TR which is needed if the river is up at all but the river bed is far faster.

Note: Described in the reverse direction to your journey

Noticeably faster walking down the valley.
