I absolutely love the TR podcast. That's where I really get value from TR. But the TR UI is as bad as Golden Cheetah, and the overall TR user experience just doesn't do it for me. If Zwift bought TR and made the workouts and plans available in Zwift, I would be a happy camper. When I was a TR subscriber last winter, I did one or two TR workouts on Zwift after I found a bunch of the the TR workouts in .zwo format. That was a nice experience, but it is against the TR rules, so... not a viable option. I also tried running both TR and Zwift at the same time, but I like the Zwift Companion app for guiding my workouts, not TR / Golden Cheetah.
I think Zwift + TR would be a terrific product fit, but from what I can tell about the management of each company, a bad cultural fit. And at the end of the day, cultural mismatches make for terrible mergers.
I hope TR finds a path that lets them focus on what they are good at (sharing their enthusiasm and love for cycling, their workouts, and the training plans), but gets them out of what they aren't so good at (software and UX).
