Nike + Running mileage is inaccurate

I'm using an iPhone 8 and my NRC app is up to date. I've removed it and re-added it, and my phone is up to date. The mileage is way off. It consistently logs more distance than I've actually run when using the map. The mile marks are off by a little over 1/10 each mile. If I'm running 10 miles, that adds up to more than a mile, a considerable distance. I've verified the correct mileage with my car. I also have tried using RunGo, and that one is spot on.

Has anyone been able to fix this?
