Since the United States is just about the only country that uses miles, all the markers along the Tokyo Marathon course will be in kilometers. There are approximately 1.609344 kilometers in a mile, so a marathon, which is 26.2 miles long, is approximately 42.2 kilometers long. Therefore, if I wanted to run a 3:30 Tokyo Marathon, I would want to run at a pace of just under five minutes per kilometer. I’m not saying that’s the pace I’m going to run during the Tokyo Marathon (it depends on how I’m feeling), but I’m trying to get used to thinking in kilometers. My next post should be from Tokyo. Hopefully, I’ll survive the long flight!
