If we put all of the marathons on one map, it would, in many areas of the world, be impossible to distinguish one dot from another. That is actually good news. It means the number of really great events is increasing rapidly. Our "dot" problem is especailly true for those cities that host multiple events each year. To make it easier to read, we have broken our directory down into 6 groupings of approximately the same size, organized by the month of the year. Click on the month(s) that you are targeting for your marathon and the appropriate map will open on your screen. To switch between maps, close or minimize the one you are viewing and select another from the above block.
You can also place your mouse pointer over the "Marathon Map" navigation bar above and the same set of choices will open below the bar. Move the pointer down and click on the month you would like to choose. That will get you to the same set of maps (we did this because not every browser can show those choices).
