What software do you use for the GPX simulations,
@Dogtrousers ?
I use RidewithGPS and Zwift. I suspect RWGPS would be capable of providing the GPX but not sure how that could be imported to Zwift. Perhaps you use something different?
I use the Tacx trainer app (Android tablet) or the Tacx desktop app (Win 10 laptop). GPX upload requires premium subscription (€10 per month or thereabouts). At the moment I'm using the free month I got when I bought by trainer (Tacx Bushido) last year. I'd been saving the free month for a rainy day, but now I think I will renew with real money when the time comes in a few days.
Today I rode a replay of the Hell of the Ashdown sportive (which I had saved in RWGPS) Now I am in considerable discomfort. I may have to get out of my chair some time later in the day, but I'm putting it off.
Other possibilities
* I've also done it - I think - by getting my Garmin Edge 530 to control the trainer . That was a few months ago and I can't remember the details. Perhaps it was a dream. No, I definitely did it. I think.
* Lastly I've signed up for RGT cycling and they are offering their premium services free during Covid. I think this includes GPX upload, but I haven't tried it yet. I'm just exploring what's possible.
Edit ...
* I think Big Ring VR may be another possibility but I haven't tried that.
* Also Bkool, see this post from

I haven't signed up to Zwift, at least not yet. There are just so many options to choose from.
