How to start running again after a long break
The trap when coming back is that your lungs recover faster than your legs. Here is how far back to start, and a four-week plan to get moving again without a fortnight off in week three.

Coming back after months off is a different problem from starting fresh, and it fails in a specific way: your cardiovascular fitness returns within a few weeks, your tendons and bones take considerably longer, and you get hurt in the gap.
How far back to start
A rough guide based on time off:
| Time off | Where to restart |
|---|---|
| Under 2 weeks | Roughly where you left off |
| 2–6 weeks | About 70% of previous weekly volume |
| 2–3 months | About 50%, with walk breaks in the first fortnight |
| 6+ months | Treat it as starting over |
These are deliberately conservative. The cost of starting too low is two boring weeks. The cost of starting too high is six weeks off.
The four-week re-entry
Assumes you had a reasonable base before. Three sessions a week, never consecutive days.
Week 1 — 20 minutes, alternating 4 minutes easy running with 1 minute walking. Week 2 — 25 minutes, 8 minutes running / 1 minute walking. Week 3 — 25–30 minutes continuous easy. Week 4 — 30 minutes continuous, and add a fourth day if the first three feel genuinely easy.
Everything is at easy effort. All of it. There is no hard session in a re-entry block, however good you feel — and you will feel good in week two, which is exactly when people ruin it.
The thing that catches everyone
Around week two or three, your aerobic system comes back faster than expected. Runs start feeling comfortable and it becomes very tempting to jump straight to your old paces and distances.
Your connective tissue is not on the same schedule. This is the single most common way a comeback turns into an injury. Hold the line for the full four weeks even when it feels unnecessary.
Check your shoes
If your shoes sat in a cupboard for a year, the midsole foam has degraded regardless of how they look. If they had significant mileage before the break, replace them — what to look for is here.
If the break was for an injury
Different situation. Do not follow the table above; follow whatever staged return your physiotherapist gave you, and if you did not get one, ask. The relevant question is not "how long has it been" but "what can this tissue tolerate now".
If the break was for pregnancy
Also different, and worth its own conversation with a professional — particularly around pelvic floor. Postnatal return-to-running guidance generally suggests a considerably longer and more staged build than most people expect, and the timeline is individual.
Being realistic about the week
The most useful thing you can do is decide which three days you are running before the week starts, and treat them like appointments. Coming back fails far more often from inconsistency than from any physiological limit — and if the schedule is the hard part, the eight-week beginner plan has a section on what to do when you miss sessions that applies just as well here.
