Known at the "Tricky Triangle", NASCAR and Indy cars continue to utilize the 2.5-mile three turn tri-oval every year, while many other lesser car groups and racing organizations have enjoyed the road course portions of the track. Ranging from .5 to 3.65 miles in length, there are 22 possible configurations. Running counter-clockwise creates 44 challenges.
