Built this Track back when Canyon came out and never really thought about uploading it but played it again today and realized that it's a pretty good track for WR hunting.
It is possible to drive it with Fullspeed but beware, it's freaking hard. I did it on my AT (which is 22:21) though.
I tried doing a new Author Time today but gave up after trying an hour and never even reaching the Finish without crashing.
So enjoy and post some replays if you make it through.
