I always had pretty simple fitness watches that just show and log pace and pulse, and that worked fine. Last year I got me a new one which is "smarter", with an app that makes predictions and asseses my fitness level, tracks "sleep quality" and stuff like that, and I came to the same conclusion, luckily without me injuring myself. I'll keep using it for just tracking, but as kind of personal trainer these things completely lack a big part of the feedback cycle about all your other body signals except heart rate, and therefore can send you down a negative, self destructive cycle of injuries.

With regard to the Marathon: Good luck, take it easy with the preparation. Don't let the pressure of investment into the Berlin Marathon (expensive registration fee etc) force you into feeling obliged to stick to plans. There are lots of other marathons and half marathons that are not as big and expensive as the Berlin Marathon, so if things go badly, just cancel it, recover, and pick another one.

Thanks! These days my body tells me what to do, so if it’s too much, then I’ll save it for another time.
