The circuit was three challenges at once: the GP is a Left Turns Challenge track, the 10 Turn course is pretty self-explanatory, and the combined road course serves as a Roval Challenge course.
I wanted to put this venue alongside the tracks near it on the 2016 SSRS calendar, but not contribute to the over-saturation of ovals in the American Southeast. So, it became located in Bayamon.
Track Map:
24 Hour Course [I'd quite like without the first chicane] (3.89 mi./6.27 km)
GP (3.17 mi./5.11 km)
10 Turn (3.09 mi./4.98 km)
Speedway Road Course (1.86 mi./3 km)
Oval (1.00 mi./1.61 km) + Drag strip (.25 mi./1.32 km)
Apparently 45247-45252 are unlucky numbers on ten-tenths.
