From debriefs and data digging, partner days and downtime, there's no time to take your foot off the pedal.
We spoke to George to find out everything he gets up to between Grand Prix weekends.
"The racetrack is the tip of the iceberg, the work that goes on at the factory is so vitally important. That's where everyone is aware of the car's performance," he explains.
There's no gentle ease into the week. Drivers will often head straight back into the Simulator, not to look ahead to the next race, but to go back over the previous weekend and see what did and didn't correlate between the virtual and real world.
It's a schedule that doesn't always agree with a driver's sleeping pattern, either.
"Take Australia as an example," says George. "I landed back in London at midnight But I'll stay on a more Eastern time schedule, rather than shift back to GMT and then do nine hours to Japan in a couple of weeks."
