Actually, just dreaming outright, it'd be very cool to be able to use the route builder that's right in Google Maps. You know, drag the start and and points, or any point in-between to specify the exact route, beginning to end. Then, an ideal would be to provide the ride creator just the sharing URL, like this: https://goo.gl/maps/ct1ewd9i6sbLCR4g7 - that might be the easiest for users while leveraging free, public Google tools for defining the route.
Alternately, one could export the route as KML to upload. It would be easy enough to parse the three placemarks from the file to get the start, end and route waypoint list. There's just a little more onus on the user to use Google My Maps to create the route and then export the KML.
I dunno - I'm just thinking about ways to make it easy to define and add rides that might not require building out some crazy web app to front it.
