This weekend the Great Britain Rowing team will take to the Olympic course at Dorney Lake to try to secure their place at the London Games this summer.

Some of the rowers have returned from overseas camps, training away from the blustery conditions at home.

BBC South Today's Alexis Green went on course on Thursday and found out that the people behind the scenes are just as important as those in the spotlight.

Alexis met GB rowing's performance director David Tanner and Team GB rowing head coach Jurgen Grobler to discuss this weekend's trials.
