Time the serious stuff starts.
"Testing, done," Lewis Hamilton said on Friday. "Let's get to racing."
Eight days of running over two weeks at Spain's Circuit de Barcelona-Catalunya threw almost everything at the teams. There was snow, freezing temperatures and heavy rain in a truncated first week. And incredible amounts of mileage for most in the sunny second.
In total, the teams covered 37,138km - or very nearly the circumference of the earth.
