Follow live coverage of the Russian Grand Prix weekend from Sochi Autodrom with F1i.
Following a difficult Friday, the teams have finally been greeted with a dry and clean circuit to complete the final hour of practice ahead of qualifying, and as a result it is set to be a busy session.
The opening practice session was shorted by half an hour following a diesel spillage which needed cleaning up, but the track was left wet and slippery in one section which prevented any meaningful running. FP2 was then a washout, leaving the teams with just this morning's session to learn about their cars and the track.
Nico Hulkenberg topped the times in FP1, but teams limited their running and a number of drivers - including Lewis Hamilton, Kimi Raikkonen and Felipe Massa - suffered spins during the hour of track time that was available.
Massa was fastest in FP2, but many drivers didn't even venture out on track such were the conditions. However, this morning's final practice session will be a different story with lots of work to get through.
Following FP1 it was confirmed Fernando Alonso - on his 250th grand prix weekend - will receive a 35-place grid penalty for power unit component changes, while Roberto Merhi drops 20 places for the same reason.
