Many thanks for your suggestion and support for TrainingPeaks Virtual.

I'm delighted to say that the latest release (v0.4.27 - which is out today), introduces a brand new experience - GPXplore.- that enables you to ride any route you like simply by uploading a GPX file, exactly as you suggest.

Initially we've opened up testing of GPXplore to everyone with a number of iconic "World Routes", and will rollout the ability to upload your own routes over the course of September. Thank you again for your suggestion, and hope that you enjoy riding whatever routes you want, whenever you want, on TrainingPeaks Virtual.
