This is the marathon season. The most popular race is the Tokyo Marathon on February 28th. However, there are road races every week during this time. Another well-known race is the 44th Ome Marathon, a 30km race that will be held just a week before on February 21st. I will run in this race, which will be my third.
The course above near Tokyo Tower and Prince Hotels is a very nice one in the heart of central Tokyo. The lengths of a couple of courses are marked. I want to thank Prince Hotel for the map.
The Prince Park Tower Tokyo
One of the most popular running routes is the Imperial Palace.
Here is a map for mobile, computer or smart phone
Below are some other good places to run in central Tokyo.
Yoyogi Park (About 2.5km once around the park)

Enjoy your run!!
