Running after having a baby: what the guidance actually says
The six-week check is not a green light for running. What current postnatal guidance actually recommends, why pelvic floor assessment comes first, and how a staged return looks.

Table of contents
This is an area to work through with a professional, not an internet article. What follows is what the published guidance broadly says, so you know what to ask for.
The six-week check is not running clearance
This is the most common misunderstanding. The standard postnatal check is a general health review. It is not an assessment of whether your pelvic floor and abdominal wall can tolerate the repeated impact of running.
Those are different questions and the second one is rarely asked.
What the guidance suggests
Expert postnatal return-to-running guidance published in recent years generally recommends a considerably more gradual timeline than most people expect — commonly suggesting that impact exercise waits until around three months postpartum, and that it follows an assessment rather than a date.
The reasoning is straightforward. Running is roughly 2–3 times bodyweight of impact, repeated hundreds of times per kilometre, through a pelvic floor that has been under sustained load for months and possibly through delivery. Tissue healing continues well beyond six weeks whatever you feel like.
This applies after a caesarean too — pregnancy loads the pelvic floor regardless of how the baby arrived.
See a pelvic health physiotherapist
The single most useful thing on this page. In some countries this is routine postnatal care; in others you have to ask for it specifically.
An assessment typically covers pelvic floor strength and coordination, abdominal separation, and a set of load tests — hopping, single-leg work, running on the spot — to see what your body currently tolerates. It gives you an actual starting point instead of a guess.
Warning signs that mean stop and get assessed
- Leaking urine during or after running
- Heaviness or dragging in the vagina or pelvis
- Pain in the pelvis, low back or abdomen during or after
- Doming or coning of the abdomen under load
None of these are things to push through or accept as permanent. All are common, and all are treatable — leaking in particular is extremely common among postnatal runners and responds well to proper pelvic floor rehabilitation.
A staged return
Once you have been assessed and cleared, the build looks much like any return from a long break, only more conservative — walking, then walk-run intervals, then continuous easy running, progressing on symptoms rather than on the calendar. The general re-entry article covers the structure; the difference here is that symptoms, not fitness, decide when you move up.
Other things that matter
Breastfeeding. A supportive, well-fitting bra becomes considerably more important, and sizing changes repeatedly in the first months — fitting is covered here. Feeding or expressing before a run is more comfortable for most people.
Fuelling. Breastfeeding plus training is a substantial energy demand. This is not a phase for a deficit — see the fuelling article and, if your cycle has not returned or you feel persistently depleted, this one.
Sleep. Broken sleep affects recovery more than most training variables. Some weeks the right call is a walk, and that is not a setback.
The honest part
The timeline in your head is probably faster than the one your body is on, particularly if you were fit before. Returning too early is the thing that most reliably delays a proper return — pelvic floor problems established early can take a long time to resolve.
There is no prize for being back at eight weeks.
