I have to say Nittany a few years ago ruined my whole season. I think I did that race and did so poorly I just dropped out for the season.
It's an "easy" race as a Cat 5 person to line up near the back and race your race. It's a "hard" race as you'll struggle while getting lapped by whatever crit racers sandbagged that day.
It's a good first race in the fact that it's easy to get to, warm and probably dry, easy to deal with parking etc. Just realize that if you're coming into it with minimal fitness to not judge all the races by that race. If anything it's a good place to just get into the hang of things early in the season if you're not used to the logistics of racing. I think people forget the stupid little shit that make racing confusing. Getting your numbers, dealing with one-day-licenses, where to stage, WHERE TO STAGE, pre-riding, etc.
If you're starting in the last 5/5 of the race you're not dealing with people slamming their bars into you. Even if you're last, who GAF?
