Personalized Running Training Plan Builder
Build an original running schedule for a mile, 1.5 miles, 5K, 10K, half marathon or marathon. Use your current running and recent performance to set the starting point, then review the sessions, assumptions and dates. This is an educational template builder, not a medical-readiness assessment or individual coaching service.
Build a schedule from your current running
Choose the event and the running you already do. The schedule uses original templates, not a validated readiness test or individual coaching assessment.
Your running schedule
Done boxes track this plan's progress. To count actual running distance in your history, add a completed activity in My Mile. Saving a plan does not add completed mileage.
How this running training plan builder works
The builder combines an event-specific preparation length with your availability and starting routine. A short-event completion pathway uses three non-consecutive timed run-walk days. Distance-based pathways use your actual weekly running distance and recent longest run. Improvement also requires a recent race performance for modeled pace references.
It doesn’t make a desired goal time determine your training speed. For instance, entering a 20-minute 5K goal with a recent 25-minute 5K keeps the pace basis tied to the demonstrated result. The desired time appears as an assumption to review, not proof of what you can achieve.
Starting requirements and supported preparation lengths
These are entry limits for the original templates. They are not universal physiological thresholds, a guarantee of readiness or a substitute for individual advice. Use representative recent weeks, rather than your highest-ever weekly total.
| Event | Completion / improvement | Improvement weekly base | Recent longest run | Minimum regular running days |
|---|---|---|---|---|
| Mile | 6 / 8 weeks | 16 km | 4 km | 3 |
| 1.5 miles | 8 / 8 weeks | 18 km | 5 km | 3 |
| 5K | 10 / 10 weeks | 24 km | 6 km | 3 |
| 10K | 12 / 12 weeks | 24 km (completion: 18 km) | 6 km | 3 |
| Half marathon | 14 / 14 weeks | 32 km (completion: 28 km) | 8 km | 4 |
| Marathon | 20 / 20 weeks | 40 km | 12 km | 4 |
Short-event completion uses walk/jog ability rather than those improvement-mileage requirements. For distance-based plans, the selected running frequency cannot exceed your established routine. Some combinations also need more volume to accommodate a complete quality session, or more available days to distribute the running.
Understand the dates, totals and sessions
The schedule contains full seven-day blocks ending on your event date. Its start is calculated backward from that date and can’t be in the past. Extra supported weeks repeat the initial foundation; a shorter deadline doesn’t remove the middle of the preparation.
All scheduled training stays on selected available days. The event itself can fall outside those ordinary training weekdays and appears once, on the chosen date. The final two days are rest days. Optional cross-training is added only to an unused available day when selected.
Peak volume and longest training run exclude the event. Timed run-walk distances stay unknown, and their session minutes include the opening and closing walks. For distance-based workouts, warm-up, repetitions, additional easy running and cool-down are included in the stated total; stationary recovery adds time without inventing distance.
What the method can and cannot tell you
The schedules are original editorial templates. Their progression, step-back pattern, entry limits and recovery choices haven’t been validated as an individual coaching model. No human coach has reviewed a generated schedule for you, and it doesn’t guarantee a finish time, score, injury prevention or event readiness.
Jack Daniels discusses training frequency, amount, intensity and recovery as distinct variables. Those general principles inform the approach. They do not validate this builder’s exact schedules. The Training Pace Calculator documents the existing equation-based performance references; they aren’t measured VO2max or official VDOT tables.
If a session doesn’t fit your present ability or recovery, shorten it, repeat a manageable stage or reassess the event. Health concerns require individual advice; this tool doesn’t diagnose symptoms. It also doesn’t prescribe nutrition, rehabilitation, strength work or every aspect of long-distance race preparation.
Keep your schedule and completed runs separate
Save to My Mile to retain one structured plan in this browser. Reopening restores its schedule and setup. Done boxes save plan progress after the plan has been saved, while regenerating makes a new schedule without overwriting the old one.
Plan JSON exports retain the schedule for local import. My Mile JSON backups retain your saved records. Calendar and CSV exports organize the planned sessions; none of these create cloud synchronization. Add a completed activity explicitly when you want actual measured running included in your history.
Frequently Asked Questions
Can I change my available weekdays?
Yes. Reopen the saved setup, change availability and generate a new schedule. Review it and save it as a new plan; the existing saved schedule remains available.
What if my chosen event date is too close?
The builder explains that the supported preparation doesn’t fit. It won’t backdate your start or compress the core weeks. A different event date or a more suitable preparation pathway may be necessary.
Can I use the improvement pathway without a recent result?
No. The numerical pace basis needs a real recent performance. The short-event completion pathways use effort instead and do not substitute an invented race time.
Does checking done log completed running distance?
No. It records progress in the plan only. Add a separate completed activity using the distance and time you actually measured.
