My goal, my rules. But Chris does get input and is my go to for official rulings when we aren't positive about something.
1 - It has to be an official race. Runner's bib, start / finish line. Any distance, any type except for a virtual race.
2 - One race may count for multiple counties. Tuna Run got me four counties over four different running legs (yes I'm counting the mile to the finish).
We are still looking for one race that covers two counties in one leg.
That's it; pretty simple really.....
