David Von Stroh submitted this ~50km route:
Run the Golden Gate Bridge and the Richmond Bridge in one go, starting from Embarcadero BART and finishing at El Cerrito del Norte BART in the clockwise direction (or reverse).
Very interested in doing this on this coming Sunday March 22. There would be 2 of us doing it, though, to replace a marathon that was obviously and appropriately canceled due to COVID-19. We will keep our distance, but we are also both male, so Im not sure what that does to the FKT record stuff.
We would be either un or self supported.
