Creating/Mapping routes on Google Maps

[Wes84]

Is there a way to map/create your routes on Google Maps / Earth while you ride?

 

I have done this by hand on Google Maps. There are a bunch of other apps like Runtastic, Endomondo & Runtastic Mountainbike (apps relate to smart phones) that track the route on Google while you ride but how do you get these routes on your Google account to then share / export them without going and mapping them again by hand?
