On top of the racing updates that will be coming in 3.20, the community has created a series of race tracks in the PU. XGR made some really cool interactive maps of them in 3D and posted them on SketchFab!
Some of these are official tracks in the PU, while others are XGRs competition tracks:
The Snake Pit - PU Track
Yadar Valley - PU Track
The Icebreaker - PU Track
Beautiful Glen Circuit - XGR Track
Baijini Blitz - XGR Track
This comes from a reddit post by MrBlackMaze:

Wow now I want to try racing!
Your link for the Icebreaker and Beautiful Glen are the same.
Thanks! Yeah it looks like the OP also had the wrong links.

I did a bit of racing when the AC modules were first released, but flight models have changed so much since then I kinda want to check it out as well.
I read about the zones that they added for racing, but haven't taken the time to check it out yet.
