Training Plan Preview

Every training plan is a deal: so many weeks, so many hours, a peak week you have to survive — in exchange for a finish time. See both sides of the deal before you commit to anything.

The estimate assumes you follow the road: the phases, the long runs, the easy days actually easy. Inside Threshold this same math re-checks itself weekly against what you really run.

How to read the road

A well-built plan isn't a straight ramp. It moves through phases — base grows the aerobic engine with easy volume, build adds threshold work, peak makes the training race-specific, and taper sheds fatigue so fitness can show up on race day. The dips in the mileage curve are deliberate down weeks: adaptation happens in the recovery, not the workout.

The two numbers most plans hide are the ones this preview leads with: the peak week and the time on feet. If seven hours in your biggest week doesn't fit your life, better to pick three runs a week now than to find out in week nine.

A note on the estimate

The finish window comes from your current 5K through Jack Daniels' VDOT tables — it's a promise anchored to evidence, not ambition. It assumes you run the plan: the long runs happen, the easy days stay easy, and you arrive at the start line tapered. Enter an honest 5K and you'll get an honest window.
