Drumsö Runt

19k long slow run around lauttasaari on Saturday. Since the shoreline of an island is supposed to have a fractal dimension greater than one, it's possible to lengthen the run by following the shoreline more closely. Here the lap around the island is about 16-3 = 13km.

Between 6-7km and slightly after 7km it's probably possible to run on the cliffs and in the woods to get a bit more distance. I'm not sure about the area around 10km, seems private with no path around the shoreline. At 12km and slightly after 14km I don't think there's a shoreline-path either.
