Valtteri Bottas returned to the top of the timesheets on an uneventful yet busy morning at the Circuit de Catalunya.
After Wednesday’s whiteout in which just 17 laps were covered, it was a busy start to Thursday’s play.
Despite the fog and the wet track, the drivers completed more laps in the first 30 minutes than the entire Wednesday.
Bottas was the man to beat as he dominated the timesheets, leading for most of the morning, on the Pirelli intermediates.
His P1, though, came under threat in the hour before lunch as the conditions improved, the rain abated and the track temperature climbed to 27’C.
