That is Eau Rouge at Spa-Francorchamps in Belgium. F1 cars take it flat out, and the compression during the uphill transition can be seen/heard in the lowering of engine rpm due to the extra load.
F1 drivers are by far the fittest motorsport drivers. Jeff Gordon had the opportunity to drive one and commented he'd have to train significantly to dream of driving one regularly. Reporters asked if he meant seat time, and he pointed out one of the F1 drivers and how thick his neck was. Not only strength and conditioning, teams are pushing for them to lose more and more weight - allows engineers more freedom to put the weight where they want it.
There are estimates that the cars could run high 8's in race form. Imagine that acceleration coupled w/ 4g lateral and 5g on decel - for numerous corners and 50+ laps. That's why mid 30s is old in the sport.
Watched the race from Bahrain yesterday, Brian Johnson from AC/DC did the podium interviews and did a great job, I think.
