which marathon competition should I run?

The world marathon majors are the six most renowned and largest global marathon competitions. The six are: Tokyo Marathon (usually in March), Boston Marathon (usually in early Apr), London Marathon (usually in late Apr), Berlin Marathon (usually in Sep), Chicago Marathon (usually in Apr) and NYC Marathon (usually in Nov). For die-hard marathon runners, it is a dream come true to run all six. Meanwhile, some marathon events are famous for their breathtaking sceneries. For Rome Marathon, you run along cobblestone streets with sights of the Coliseum, St. Peter’s Square, and the Spanish Steps. The Great Wall Marathon in China is one of a kind race as runners climb the steep steps while enjoying the views rather than running on paved road. The Antarctica Marathon could be your most challenging and hard to reach marathon destination.The course is on King George Island. Runners run with penguins, seals and whales as their companions. The Big Sur Marathon in the US has its course on scenic Highway 1, the iconic Bixby Bridge marked the halfway point of the race, where runners can enjoy the unique site and a pianist performance!
