Best Pace and Corral Updates

We use a formula to predict your best pace and make your corral assignment. The formula converts a race time to an equivalent 10K time, and the pace from that time becomes your best pace (see chart below). Only NYRR races 3 miles or longer and within a rolling two-year timeframe are used to determine your best pace. If the race that stood as your best pace expires after the rolling two-year timeframe, a new best pace will be calculated when you complete your next NYRR race. Read about pace cuts here.

You can view your best pace on your Dashboard when you log into your NYRR account.
