There’s no simple way to use training data for race pacing. It all depends upon the length of the race. On race day you are going to be rested and excited and it is easy to get swept up with the pack. So, chances are good that you will start out too fast for your own good. You’ll likely need to consciously “hold back” when you start.
Even in the shorter races that we tend to address like a VK or Skimo it is entirely too easy to go out too fast thinking that you are loosing time to your rivals. Both real world empirical data and studies have shown that starting out too fast, even by just a few seconds/km will usually translate to a slowing by many minutes/km in the final stages of the race.
In the end I think pacing is one of the “dark” skills of racing that can only be learned through trial and error.
