So the question is I assume I trust the treadmill more then the Watch? I want to have the most accurate times when training and running for all these events.
Having all this info tonight I will do another run with the same amount of time but this time with 15/30 (my normal pace) and see how it changes things as well as if I should start using 30/30.
Depends. Don't think the Apple watch is known for accuracy when compared to say a Garmin, especially if you are using it on a treadmill, where it's not getting GPS readings.
If you use the same treadmill all the time, then if it is off, it will be off consistently. But if you use different treadmills, then it will vary. The belts on treadmills do slip at times, so even if its the same model and such, the wear and lifespan of the belt & tensioning (I think) can cause it to vary.
If you can use a track that has a marked known distance, and see what the Apple watch says, that will help you to see how accurate it is. Ideally the GPS would be turned off, so that it handles the distance the same as if you were on a treadmill, by doing stride length and such. No idea if you can calibrate them, sometimes you can calibrate things like that.
Personally, it's more of a thing you learn over time. Stick with the same measurement as much as you can. If & when you can do properly measured races, with chip timing, then compare how that works out and go from there.
