This outline is the skeleton. Gritup makes it yours.

A printed plan can't know that you were travelling last week, that your long run felt awful, or that your fitness jumped. Gritup takes this exact structure and makes it adaptive:

  • Calibrated to you. Paces and zones set from your recent results, not a generic label.
  • Adapts when life happens. Miss a session or a week and the plan rebuilds the path to race day.
  • Fits your real schedule. Choose your training days, and the plan reshapes around them instead of the other way round.
  • One app, every sport. Run, bike, swim, or combine them for triathlon, without juggling separate apps.

Frequently asked

How many days a week is the 12-week advanced half marathon plan?

This plan runs 6 days a week over 12 weeks, structured in base, build, peak, and taper phases. If 6 days doesn't fit your week, Gritup can rebuild the same goal around the days you actually have.

Is this half marathon plan right for a advanced athlete?

Yes, it's written for a advanced athlete. It assumes you already have a training base and layers in threshold and race-specific work. In the app, the plan calibrates to your recent results rather than a one-size label.

What happens if I miss a session or get sick?

With a static plan you're on your own: shift the week and hope the balance still works. Gritup re-plans the remaining weeks around a missed session, an injury, or a busy stretch, so you always have a coherent plan to race day instead of a broken schedule.

Is this training plan really free?

Yes. The full week-by-week outline on this page is free to follow. Gritup itself is a subscription that turns this skeleton into an adaptive, personalised plan, with a free trial and no card required to start.
