Word is that MyWhoosh will be adding an API yet this year (2024). Let me know if you'd like me to put you all in touch with one of their product managers :-)

When my Zwift subscription runs out later this year, I have no intention of renewing. It's not worth the cost to me. I'll use MyWhoosh for free for my indoor training sessions towards the end of 2024 and on.

I would LOVE to see the FasCat app be able to push workouts to MyWhoosh, as well as pull MyWhoosh activities into the app for analysis.
