Odd shaped tracks

I remember a thread on here a few months ago about schools that have abnormally shaped tracks. I am trying to find the thread for a research project my geometry students are working on.

Any help would be much appreciated. Thanks.

Is this what you were thinking of?

This one looks challenging:

The thread was actually about running tracks. Most were in inner cities where the size of the school’s playing fields would not allow for a traditional running track. One looked like an egg, another had a pretty close to 90 degree turn, etc…

Although I would love to ride on that track.
