Half marathon training that fits real life
Most training plans don't survive real life.
Sticking to a half marathon plan is the hard part — so we built a plan that adapts to your level, your goals, and the days you can actually run. Tell us about your race and we do the rest.
$19.99 intro price — only 100 places left, then $34.99. Pay once per race. No subscription.
Your routine is taking shape. Keep breathing easy on every run and protect the rest days that sit between your harder sessions. Twelve weeks gives you time to layer base miles before structured quality appears.

Log a run, the plan adapts.
Your actual paces feed back into your VDOT each week, so every session stays calibrated to how you're really running.
A real plan from our engine — built around your training weeks, experience, and the days you run.
How it works
Three steps to your finish line
A plan you can actually stick to — built around your life, not a rigid template.
Tell us about your race
Race date, your goal, the days you can run, and when your long run fits best. It takes about two minutes.
We build your plan
Your plan lands instantly: base, build, peak, and taper — with exact paces, intervals, and recovery weeks laid out day by day.
Run. Log. Adapt.
Log each run and your plan recalibrates. Future paces and workouts update to your actual fitness — not a one-time guess.

The method
A method that adapts to you
The training is structured, but the numbers are never guesswork. Your fitness becomes a single score — VDOT — that drives every pace in your plan, from easy runs to repetitions.
Periodized for race day
Base, build, peak, taper. Your hardest weeks land before the taper, so you cross the start line fresh — not fried.
Hard days hard, easy days easy
An 80/20 split of easy volume to quality work keeps you building without breaking down.
Built around the days you run
Tell us which days work and when your long run fits — the plan bends to your schedule, not the other way around.
Paces stay honest as you improve
Log your runs and your VDOT is recalculated from your actual training. Keep progressing, and the plan keeps up.
How your paces update
after 6 weeks of logging runs
Easy run
Tempo
Long run
Your VDOT moves with you. As your logged runs show real fitness gains, easy, tempo, and interval paces tighten — so you're always training at the level you're actually at, not the level you started at.
Half marathon training guides
Start with the question your plan cannot answer for you.
How many weeks do you need? Is your easy pace actually easy? What should change in the taper? Use the source-led library to understand the decision before you apply it to your training.

“I've started three plans over the years and quit all of them. This one fit the days I actually had free, and logging every run kept me honest. Finished my first 21K in June.”

“The paces recalibrated every week from my real runs. When I hit a rough patch, the plan backed off instead of burying me. That's exactly why I stuck with it.”
