Most races I saw were one run only. However, there were numerous times when two cars raced, then negotiated starting distances, etc. to see if they could even things out in a second race. I remember one night at Vancouver Lake, when these two slow ass honda civics raced eight or nine times, as both cars were dead even. People became annoyed because these two kept holding things up. Yes, the bickering always occurs. However, there are the occasional multiple races in succession between two parties.
