What's inside
A coach on every page.
- Your own paces. Take a 1.5-mile test, find your row, and get four personal paces — easy, long run, threshold and race.
- A page for every day. Each of the 84 days tells you today's run, the distance and pace, and why that session matters.
- Coaching notes, built in. "Why this week looks like this" pages explain the thinking behind each block, so you understand the plan instead of just following it.
- Track what actually happened. Log distance, pace, time, weather and effort every day, with guidance on what to change if a run felt too easy or too hard.
- Race week and after. Your last seven days, a race plan, the two weeks after, and a worksheet for building your own next block.
Who it's for
Runners who can run three times a week and want to finish their first half marathon healthy and confident — no guessing, no copying someone else's plan.
