What are the best apps to use to plan a marathon training course?

Last year when I was training for my first marathon, I looked around to see if there were good apps or online tools in order to help me map out my long runs.  Turns out, I don't live in an area where people really like to use social apps.  Come to think of it, most local businesses don't even have yelp reviews. What I found to work the best was just to use the measuring tool on Google maps to brainstorm paths to run around.  I've ended up creating some "signature runs," which I have enjoyed so much that I make sure to do from time to time when I'm home.

It can even give you an status when you reach certain milestones. And after your run you can look up your stats and running history online. Also you can make courses online to match up with the runs you have done if you can't use GPS on your phone. Personally I love this app. Keeping track personal bests really helps motivate me to beat them. And I love seeing the charts in which I can see how I have improved.
