Persistent rain severely limited running during second practice for the Belgian Grand Prix, with Charles Pic setting the fastest time by virtue of a last minute lap to the grid to perform a practice start.
It took 48 minutes for the first car to emerge from the pits and when Nico Rosberg did hit the track he was confronted by several rivers flowing across it. Running was severely limited as a result with one car tentatively edging its way around the track at a time.
Only ten cars set lap times and they only came at the end of the session as the cars pulled up to the grid to complete practice starts. Pic's lap just so happened to be the fastest by 0.396s from Daniel Ricciardo but nothing should be read into the times.
Remarkably none of the drivers had major incidents, although Heikki Kovalainen and Timo Glock were among those completing a pirouette at Les Combes as they struggled to control the cars over a small stream running across the circuit.
The limited track time should make for a busy session on Saturday morning when the sun is forecast to return to Spa-Francorchamps. Most teams have brought updates to the track, but Marussia opted not to run its new parts in FP2 in case one of the drivers had an accident.
Mark Webber, Kimi Raikkonen, Romain Grosjean, Vitaly Petrov, Pedro de la Rosa and Narain Karthikeyan did not bother setting a time.
