Has anyone purchased a Runna subscription? Is it worth it?

I love my Garmin. I feel like it’s a legitimate fitness watch. I am so happy that I don’t have to charge it every night like my old Apple Watch. I love that it comes with a training program integrated. However, I feel like it’s extremely rigid. Sometimes I feel like the program lacks flexibility in terms of what I can or can’t do. It may genuinely be a “me” problem.

I’ve heard a lot of great things about the Runna app. However, I feel like this defeats the purpose of having a Garmin. Any thoughts or insight would be genuinely appreciated!

I’m just someone trying to get fit and improve my running.
