Hi - maybe someone has thought of this already - or maybe it even already exists - I have a suggestion for custom workouts; basically take a real life route (.gpx file) and turn it in to a custom workout so you can train for that specific route.
Anything like this out/in the pipeline?
Thanks
How would the route file translate into a workout?
You can do this using bestbikesplit and the workout creator! basically just input your rider+ bike data and search for the course on BBS. It’ll give you an option to download the file, which you can then click and drag to workout creator 
That being said, I know there was a podcast episode on why training with ‘course replica’ workouts isn’t a great idea. Personally i’m just doing it because there’s no race 
More or less covered as a non-direct solution here.
