Half marathon training plan

Your half marathon training plan

A structured plan to run a strong half — a growing long run for endurance, threshold and tempo work at race pace, intervals for sharpness, and a taper — built around your week and adapted as you log.

Built for 21.1K, not a generic running block

The half marathon is an endurance race held at a real pace. Your coach builds a periodized plan with a long run that grows sensibly, threshold and tempo work to settle your race pace, intervals for sharpness, and a taper so you arrive fresh.

Each week has a purpose, and your coach explains it — why the long run grows the way it does and why race-pace work shows up when it does.

Built around your level and your days

Whether it's your first half or a new PB, the plan is shaped by your current pace, your longest comfortable run, and how many days you can train — not a template that assumes mileage you aren't running yet.

Adapts to how your runs actually go

You log your runs, and your coach guides mileage and intensity from there — building the long run and race-pace work toward your goal, and easing off with a recovery week when it's time to absorb the load.

Frequently asked questions

It's my first half — is that okay?
Yes. The plan builds your long run and endurance gradually from your current level, so the distance feels manageable well before race day.
How long is the plan?
It's sized to your goal and starting point. If you give a race date, the plan fits the block and times the taper to it.
Does it use effort or pace zones?
Sessions are prescribed by effort so you train at the right intensity for each run — easy, race-pace, threshold and intervals.
Is it free?
