Pick the default variant, scan the phase map, then use one tool to lock pace and fueling numbers.
1. Choose a variant
3 days/week (Beginner-friendly)
Start with the recommended default. Customize only after two consistent weeks.
2. Scan the phase map
Base → build → peak → taper

Pace + fueling defaults
Run one calculator now so race week is execution, not improvisation.
Jump to toolsPlan length
10 weeks
Built with phases, cutbacks, and a taper you can actually execute.
Weekly rhythm
3–5 days/week
Choose one variant and follow it for 2 weeks before tweaking.
Typical session time
Easy: ~40m • Long: ~75m
Prefer consistent minutes over heroic single sessions.
Readiness gate
Default recommendation
3 days/week (Beginner-friendly)
Start here to reduce decision fatigue. Customize only after your first two weeks feel stable.
This is general training information, not medical advice.
Coaching beta
Get coach-style adjustments when you miss sessions, sleep poorly, or feel fatigue signals.
Pick a weekly rhythm you can repeat consistently. Start with the recommended default, then adjust only after your first two weeks feel stable.
3 days/week (Beginner-friendly)
4 days/week (Balanced default)
5 days/week (Advanced, recovery-dependent)
Pick a days/week variant you can repeat without drama. Keep easy runs truly easy so you can execute the workout and long run consistently.
Glossary (useful concepts):
Week by week
Use this as your decision map: what matters this week, what the long run is doing, and where you should back off.
Weeks 1–3
Build consistency and mechanics; keep easy days easy.
Long session: 45 min long run (easy + relaxed strides)
Weeks 4–7
Add threshold work while protecting recovery.
Long session: 51 min long run (easy; finish steady when recovered) • Cutbacks: 1
Weeks 8–9
Sharpen race-specific speed without racing workouts.
Long session: 1h 8m long run (easy; add controlled steady blocks) • Cutbacks: 1
Weeks 10–10
Reduce load; keep rhythm; arrive fresh.
Long session: 1h 8m long run (short + relaxed strides)

Workout library
You don’t need 50 workouts. You need a small library that you execute consistently, then progress safely.
Purpose: Build volume without accumulating fatigue.
Prescription: 25–55 min at conversational effort. If you can’t talk in full sentences, it’s too hard.
Substitutions
Red flags
Purpose: Improve mechanics and economy without a heavy metabolic cost.
Prescription: After an easy run: 6–10 × 15–20 sec fast-but-relaxed, full walk/jog recovery.
Substitutions
Red flags
Purpose: Raise sustainable pace and teach controlled discomfort.
Prescription: 2–4 × 8–12 min at ‘comfortably hard’ with 2–3 min easy between.
Substitutions
Red flags
Purpose: Improve speed and economy without turning every session into a test.
Prescription: 5–8 × 3 min hard with 2–3 min easy; finish with form, not desperation.
Substitutions
Red flags
Purpose: Practice race-specific rhythm and pacing discipline.
Prescription: 8–12 × 400m at controlled 5K effort with 200m jog; keep the first half conservative.
Substitutions
Red flags
Purpose: Build durability and the aerobic base that supports faster running.
Prescription: Mostly easy. When stable: finish the last 10–20 min steady (not a race). Add strides occasionally.
Substitutions
Red flags
Purpose: Support durability and running economy with minimal interference.
Prescription: 2×/week, 20–35 min: hips, calves, hamstrings, trunk. Leave 1–2 reps in the tank.

Adaptation rules
Most training failures are not fitness failures — they’re pacing, sleep, or scheduling failures. Use simple rules.
Tools
Pick one tool, generate outputs, then plug them into your training week.
Evidence (high level)
For many runners with a base, yes. If you’re building durability from low volume, extend the timeline and keep intensity conservative.
A good default is one quality workout plus one long-run focus. If you add a second quality session, keep it short and only when recovery is stable.
Yes. Long runs build durability and aerobic capacity, which makes your speedwork more effective and your racing more repeatable.
Easy means conversational. If you can’t talk in full sentences, slow down or add walk breaks. Easy days are what make workouts possible.
Don’t cram. Keep the next session easy, protect the long run, and resume structure when your legs feel normal again.
Two short sessions per week is a high-ROI habit for durability. Keep it consistent and avoid leaving yourself sore for key runs.

| 3 | 3 | 15:00 |
| 4 | 4 | 20:00 |
| 5 | 5 | 25:00 |
Assumptions: steady pacing; no terrain/wind adjustments. Use this to plan, then calibrate by effort in real conditions.
Calculator
Start with one recent performance, then estimate equivalent 5K / 10K / half marathon / marathon times. Useful for goal-setting and workout planning.
Default 1.06. Higher = more slowdown as distance increases.
Known result
Predicted half
A good checkpoint for endurance readiness.
Predicted marathon
Assumes you train the endurance + fueling required.
| Distance | Predicted time | Pace / km | Pace / mile |
|---|---|---|---|
| 5K | 25:00 | 5:00 | 8:03 |
| 10K | 52:07 | 5:13 | 8:23 |
| Half marathon | 1:55:00 | 5:27 | 8:46 |
| Marathon | 3:59:47 | 5:41 | 9:09 |
This is a simplified model. It does not account for heat, hills, fueling, or whether you’ve trained the durability needed for longer races. Use it for planning — then execute by effort.
