Is there a map application that includes route and distance?

[MacGirl88]

I love the website MapMyRun and I was wondering if anyone knew of any apps that are similar but for the iphone or ipad (I have both). MapMyRun doesn't allow you to draw and plot runs directly through the app, you still have to go to their website, map it out there and then download them. I need an app that I can do all of that within the application itself. Then it would be nice if I could take a snapshot and email those runs to other people

Basically, does any one know of any great mapping apps that plot distances and you are able to manually draw routes on?

Thanks!
