I took a the Yamanote Line train (which runs in a circle around Tokyo) and after about 20 minutes, it had counted 2.5km of travel. If you have anything local that's similar, should work. You can hit pokestops on the way too.All this talk of eggs, has anyone figured out the best way to actually make the app track your movement yet? Especially if you're biking it around. The weather is almost tolerable a little bit here some of these days and finally have my bike back so there's potential to put a little more energy into this nonsense.
Alternatively, I've heard putting your phone on a model train going around a track, on a vinyl spinning around, or attached to a ceiling fan works to varying degrees as well.
Edit: Roomba works too!
