Using GIS to create runs. Ask it the distance you want to run and the amount of climb, and it'll come back with a route.
And get it to put in a few Strava segments on the way.
I actually have something like that on my mind map document of ideas. I'm kind of leaning more towards integrating GIS and RS with the concept though as it shows employers that you know how to work with both independent of one another and as an integrated programme. But there is a component which would calculate routes associated with the previous output generated. I hope!
