We still believe that when in Rome, you should run a marathon. We were already inspired by the documentary about the Midnight Mission Runners who took the journey from homelessness in L.A. to running the Rome Marathon, and now we think you should add this race to your bucket list. There are lots of reasons why Rome is one of the most visited cities in the world: the culture, the history, the art, the locals, and everything in between. Minus a couple of spots, the race is relatively flat, which makes for a fast course through beautiful, historic structures. The marathon has increased in numbers over the past few years, last year totaling almost 14,000 participants.
