I’ve just made and account and imported some runs to have a look.

The layout and stats all look fresh, new and modern but the absolute deal breaker for me is the lack of a planning calendar. As life makes a mess of my training plan it’s really important to be able to quickly and efficiently swap sessions out. Maybe this feature will come to Runalyze in the future.

I wouldn’t use CTL or ATL to diagnose overtraining. It’s a lot more nuanced than what two generic metrics can capture.

Sorry, I don’t follow. Suggest for what? Avoiding overtraining? That article does a good job of describing it.

The best thing is to intentionally undertrain. With a margin of safety, you don’t have to worry about it. And by staying healthy longer, your overall progress will be better in the end.
