Or get passed by.
I know you're clowning around, but don't forget that this isn't a race. It's going to be a crowded track on Sunday, and with only two run groups there is going to be a potential for some pretty big speed/skill differentials. Thankfully ECR isn't a very complex track, so you'll have plenty of time on the four major straights to check your mirrors for traffic.
I just got an email from Maggie with the latest count:
47 on Saturday
60 on Sunday (Sunday is full)
