This Google Map shows your 100 Mile, 100K, and 50K start and finish lines.  It also shows all of your Aid Stations and water stops.  Click on the icons to see what's available at the different locations, as well as crew instructions, in the Description.

Also below is a video with instructions about how to copy the map, make it available offline, and create a custom list for your crew and pacers to use to navigate to you race weekend, even when there's no cellular service.

We suggest waiting to do this until maybe two weeks before the race in case we need to make any small changes to the map. But don't wait until two days before the race. This is something that takes some time to do, and you should probably go over how it works with your crew to ensure they understand.
