Is the race timed the same for NB+ registrants?

Yes. The San Francisco Marathon uses ChronoTrack live to track runners’ times. This tool already has three timing categories (M, F, and Non-Specific) built in. We post all results in Athlinks, which already has M, F, and NB as three different categories. These categories all support age divisions and awards. In short, timing within three categories will work just as it did when we had only two categories.
