You are talking about the rahway river park training crit. This goes on tuesday evenings for a while. I have attended a couple of these sessions. They are definitely a good way to get some high intensity work in during a small amount of time.
I attended these with very little miles under my belt. I dont even think I knew what a crit was. I was in a bit over my head:hmmm:
I was having a discussion about this very event the other day. I will give the following disclaimers: The pace is fast. Beware of pain.
Anyone is can get in the mix here. Yahoos like myself with no experience riding in a pack can present a serious danger to the him/herself and the others around him. Stay clear of the guys who cant ride in a straight line or over react to the situations in front of them. Keep your eyes up on the road and riders ahead. You will keep yourself out of danger.
I guess the point of it all is to be safe and you will come away with some valuable training.
