Frequently asked questions

Do I need to create an account?

What if my race is less than 12 weeks away?
We can generate compressed plans from as short as 8 weeks, though we'll flag if your timeline may be too aggressive based on your current fitness.
Can I adjust the plan after it's generated?
Yes. You can move sessions between days, skip a week, or regenerate with different inputs at any time.
Is this really free?
Yes, the core plan generator is completely free. We may offer optional premium features in the future, but a full training plan will always be free.
