Build confidence in the longer outings while keeping the rest of the week pleasantly ordinary.
The aim: complete the distance with a rehearsed, manageable approach. This is an original Running Woman template, not a personalised prescription or a trial-tested programme.
Running Woman takeaway: Pick the plan whose first week looks familiar, not the one whose title sounds the most impressive.

Before you begin
Start only when you can already sustain about 170 minutes of running or deliberate run-walk sessions per week, across 4 days, with a comfortable recent outing of at least 65 minutes. This pattern should have been reasonably consistent for 8 weeks. A single unusually busy week does not count as a base.
These are Running Woman's conservative editorial matching rules, not validated thresholds that prove safety. Review your actual recent training, current health and the week-one schedule together. The required experience also includes a comfortable completed 10K.
Do not use this as injury rehabilitation, a return after significant illness, or a pregnancy/postpartum clearance programme. The health and women's-running guide explains the boundaries. Seek urgent help for severe symptoms; ordinary training decisions can wait.
Why this distance and duration need this approach
A half marathon is 21.0975 km. The commitment is not just the Sunday outing: the surrounding easy sessions, ordinary meals and recovery space need a place in the diary too. First-time plans prioritise covering the distance, while improver plans introduce controlled sustained efforts. Neither requires a hard rehearsal of the full race before race day.
The longer calendar gives more opportunities to consolidate, rehearse and repeat a week. It does not make every increase compulsory. Extra time is most useful when it lowers the pressure to force progress, rather than becoming permission to add more hard sessions.
How to read the schedule
E is easy running, L is the longer easy outing, RW is run-walk, W is comfortable walking, TR is easy trail run/hike and H is a hiking session replacing a run. The number is the complete session duration in minutes. Easy means conversational and controlled, roughly 2 to 4 on an informal 0 to 10 effort scale. These are descriptive cues, not measured physiological zones.[1]
For E, L and TR, the first and last five minutes are deliberately gentle and already included. RW includes five minutes walking at each end, with the week's ratio used only in the middle. Shorten the final run-walk cycle to finish on time. For an ordinary easy run, use a walk break whenever it is needed to restore easy effort, without adding time to make up for it.
A named workout such as T3x5 is fully specified below the table. The total includes every recovery. An additional “+ S20 optional” is a separate 20-minute strength slot, not running time. “Rest” means no prescribed session, not a ban on ordinary comfortable daily movement.

What to focus on each week
Week 1: Settle in. Keep the effort easy and note how you feel the following day.
Week 2: Build / practise. Keep the effort easy and note how you feel the following day.
Week 3: Build / practise. Keep the effort easy and note how you feel the following day.
Week 4: Cutback. A deliberately lighter week. Do not replace the removed minutes with another hard activity.
Week 5: Build / practise. Keep the effort easy and note how you feel the following day.
Week 6: Build / practise. Rehearse food, drink, clothing and the route. Log elapsed time and actual distance, including stops.
Week 7: Build / practise. Rehearse food, drink, clothing and the route. Log elapsed time and actual distance, including stops.
Week 8: Cutback. A deliberately lighter week. Do not replace the removed minutes with another hard activity.
Week 9: Build / practise. Rehearse food, drink, clothing and the route. Log elapsed time and actual distance, including stops.
Week 10: Build / practise. Rehearse food, drink, clothing and the route. Log elapsed time and actual distance, including stops.
Week 11: Build / practise. Rehearse food, drink, clothing and the route. Log elapsed time and actual distance, including stops.
Week 12: Cutback. A deliberately lighter week. Do not replace the removed minutes with another hard activity.
Week 13: Build / practise. Rehearse food, drink, clothing and the route. Log elapsed time and actual distance, including stops.
Week 14: Build / practise. Rehearse food, drink, clothing and the route. Log elapsed time and actual distance, including stops.
Week 15: Taper. Reduce training, retain familiar routines and do not add missed long runs.
Week 16: Event week. The event is separate from the training-minute total. Completion is conditional on readiness and current health.
Session instructions
There are no compulsory faster workouts in this plan. The developing routine and the longer outing are the training task. Do not add intervals from another article just because the week looks simple. Simple is allowed.
S20: an optional 20-minute support session
Use a familiar, modest routine: about 3 minutes of easy preparation, then 12 minutes alternating a comfortable squat or sit-to-stand, a supported step-up or split squat, a hip hinge or bridge, and calf raises. Leave several comfortable repetitions in reserve. Use the remaining 5 minutes for a familiar upper-body pull/push or easy trunk exercise, plus a gentle finish. Start with one set of each movement; familiar trained runners can use a second set within the same time. This is not maximum-strength testing. Choose loads and movements with competent instruction where needed.
The slot is optional. It is not a prescription to start unfamiliar loaded exercise during a demanding running week. New pain, marked soreness or poor recovery means reducing or omitting it. Strength evidence and progression are explained in the support-training guide.
Move days, not the purpose of the week
You may shift the entire week to suit work or family life. Preserve the number of outings, a genuine recovery opportunity after the longest or harder session, and the relationship between sessions. A four-day plan is not a three-day plan with two runs combined. Do not add a fast parkrun to a week that already contains the named workout: it would replace that workout, and the surrounding schedule would need adjusting.
Where a Sunday event must move to Saturday, move the final week's sessions together and retain an easy/rest day immediately before it. Do not simply add a Saturday race on top of the Sunday long run. The weekly scheduling guide gives examples.
Readiness checkpoints, not pass-or-fail tests
Before tapering, review recent comfortable long outings around 16 to 18 km alongside the whole week, your recovery and the event cut-off. This is an editorial discussion range, not a proven universal minimum. When the plan's time allowance does not provide comparable exposure at your comfortable pace, arrange a longer or individualised build rather than silently adding an hour.
The longest outing is capped at 150 minutes in this template. This is a workload-design choice, not a universal safe maximum and not permission to ignore symptoms before that time. Do not run faster to reach a distance inside the cap. An event can still be a substantial increase beyond training exposure. Meeting the plan does not remove risk.[2]
Review the plan every week. Continuing is reasonable only while the ordinary pattern remains manageable, the longer outings do not cause persistent problems, and the event logistics remain compatible with your likely pace. A coach or clinician may advise changing the plan; their individual assessment takes precedence over a generic table.
When a week does not go to plan
A missed session is not carried forward. Resume with an easy session when well enough, then decide whether to repeat a week or move the event goal. After a longer interruption, reassess against the entry checks instead of returning automatically to the calendar's current week. See missed sessions and interruptions.
Stop a session for pain that changes how you move, or symptoms that feel unusual and concerning. Persistent focal pain, ongoing unusual fatigue, menstrual disruption or pelvic-floor symptoms deserve appropriate assessment. These plans are not weight-loss programmes and do not ask you to earn your meals.
The finish and what comes next
5 min easy walking before and 5 min easy walking after, separate from race time; use event guidance and your normal routine. That adds 10 minutes, separately from the race and the final week's training total. Do not extend a cool-down when unwell; follow the event medical team's advice.
For a first finish, begin with the easy run-walk or running approach you practised. Check the organiser's current cut-offs, including intermediate ones, and count stops in elapsed time. Afterwards, let walking, normal meals, rest and your symptoms guide the early recovery. There is no automatic hard session seven days later and no obligation to book a longer race immediately.
Evidence and limits
The schedule, entry checks, session combinations and calendar length are Running Woman editorial constructions. They have not been tested together in a clinical or performance trial. The evidence trail includes training-plan structure[3], load measurement[2:1] and tapering principles[4]; those sources do not establish this exact plan as optimal. Detailed findings, populations and limitations are in the evidence guide.
