Sprints 1 and 2. These are PCA stock classes E,F,G and H. E is the slowest and H is the fastest. Multi-class racing makes for some interesting situations. You can find yourself racing a car not in your class just to get to a car in your class to race. It can be a lot of fun. The enduro group was broken up differently where E class was the fastest.
Sprint 1 has a lengthy caution as one driver bounced off the SAFER barrier in turn 11 and came back across the track to collect a very well driven E car. Sprint 2 only had some local yellows. That was a lot of racing!
All in all, the Glen is always great and every time I go I get a little better.
