Stadium is probably not built roughly like this but it's more styled like my snowtracks with lots of microtransitions. You have to brake quite a lot in the curves which is not too much of a flowcrasher I hope.
It's pretty easy to build small transitions with the free blockmixing mode (the third one) but takes ages to build up a decent scenery. Feels like putting the entire universe piece by piece together. The first 20 seconds of the tracklayout belonged to my track "Pyra" from TMUF-X.
