"I'm training for a marathon — how many kilometers should I run per week?" Start from where you are right now. If you're running 15 km a week — that's exactly where you should begin.
But most people want to know how much they need to run each week to be ready for a specific race. Or, for example, how many days per week they should be training to finish a marathon two months from now.
In other words — if you're not sure where to start, just ask Rob. He'll give you recommendations based on your data.
Rob will look at your profile, check your current numbers, and give you recommendations based on your goals and ambitions. He won't change your settings — we haven't allowed that yet. The decision is always yours.
Beyond volume, Rob can also suggest optimal preparation timelines, a target race date, the number of training days per week, and other parameters from your Settings.
Ask, learn, think it through. And remember — your health is your responsibility.
