Ohio Valley Region, the SCCA chapter behind the event, had a mandatory track walk for novice racers. An experienced driver in the group took beginners through a turn-by-turn walking tour of the track. I found it extremely helpful for learning the track, but I found myself getting a little overwhelmed by the level of multitasking I was going to have to do.
Autocross tracks like this are relatively small and low speed, but they require high precision and tight timing, which was explained in detail during the track walk. Every corner had a specific entry point to set up for the turn after it, the one after, and so on. It made me realize how quickly putting a tire wrong in one corner can soil an entire run.
