My question is mainly for locals... or those who know the expected routes on March 23rd (Rome Marathon day).
I will be at the Colosseum and Roman Forum on that day (expecting to finish around Noon).
What would you think is the best way to travel on that day; from the Colosseum area to Campo de' Fiori area?
One note - Not by foot!
Any suggestion will be good (since I expect public transportation to be corrupted).
