I’m running the Chicago Marathon this weekend and wanted to use the Pace Pro
But knowing the GPS in Chicago… it really doesn’t work so you have to lap the miles! Do you know if you can lap miles in Pace pro and it still work?
hope that makes sense ¯\_(ツ)_/¯
I don't think there is a direct correlation to your watch generated lap (auto or manual) to the splits for PacePro. DC Rainmaker has a nice writeup on the f6 with a section dedicated to the PacePro feature.

Basically, if Ray is correct, PacePro keys on the actual location of the split as defined by the preloaded route (I assume you are using the Marathon route as your basis to calculate you PacePro Plan), not the distance calculated by the watch. I have example data below of a recent half marathon that seems to prove Ray's description (no snickering at the slow pace, I'm an old man). The first screenshot is the list of the auto laps (miles) generated by the watch (the first green highlighted was an accidental manual lap) and are exactly 1.00 miles (measured by the watch). The second graphic shows the PacePro results. Each of the PacePro splits are measured by the watch to be close to a mile, but not exactly 1.00 mile. This makes sense if the PacePro splits are tied to a location and not the measured distance from the start or last split. With that said, I don't know how well PacePro will work in your urban canyon situation, but I'm pretty sure that PacePro split calculations would not be correlated to you pressing the lap button at each mile.
