Rain falls mainly on Portugal plain
But today's session was somewhat of a washout as the riders could only manage to piece together three or four laps before being interrupted by showers, which did not allow the track to dry out.
Today's action however did see Ruben Xaus get to grips with his Ten Kate Honda for the first time since signing for the Dutch team, while James Toseland had an opportunity to ride the BMW test-team bike while his BMW Italia machine is being prepared (Images: Kel Edge Photography).
The laps times were all around the high 1.57"/ 1.58" mark, with Honda's Jonathan Rea clocking the best of the day ahead of Haslam and Corser.
Tomorrow hopefully conditions will improve for the second and final day of testing.
