When can you start running again after a baby?
For most women, high-impact running is best held until around twelve weeks postpartum, and guided by how your body responds rather than the calendar alone. Expert return-to-running guidance for postnatal women points to a staged rebuild of pelvic floor and core strength first, ideally with a pelvic health physiotherapy assessment. A cesarean or a complicated birth can mean longer. This is general information, so let your own clinician set your timeline.
Why lead with the pelvic floor?
Pregnancy and birth stretch and load the pelvic floor and abdominal wall, and they do not snap back overnight. Running is repeated impact and downward pressure, so going straight to it before that support has rebuilt is what drives leaking, a feeling of heaviness, or pain. Building pelvic floor and deep core control first gives your runs something to land on.
How do you rebuild toward running?
Breath and gentle activation
Start with diaphragmatic breathing and gentle pelvic floor lifts with a full release, reconnecting the floor and deep core. This is the foundation, and it can begin gently in the early weeks.
Load and impact, gradually
Progress to walking, then loaded carries, single-leg work, and low-level impact such as hops, watching how your body responds at each step. Only then layer in walk-run intervals. If a stage brings on leaking or heaviness, drop back a level and rebuild.
Watch for the warning signs
Leaking, a dragging heaviness or bulge, pelvic or back pain, or a doming along the midline of your belly all mean back off and get assessed. They are signals, not verdicts, and a pelvic health physio can get you back on track.
A pelvic health physiotherapy assessment is the single most useful step in a postpartum return to running, and it is worth seeking even if you feel fine. See your clinician about any leaking, heaviness, bulge, or pain. Phaes is informational and is not medical advice.
How Phaes helps
Phaes is built around adapting training to a woman's body, and a gradual, symptom-led return is exactly that. Track how you feel as you add load and impact, keep the ramp sensible, and let pelvic floor and strength work lead before the runs do. As your cycle returns, Phaes folds it back in as a training input. Explore pelvic floor exercises for runners or take the 2-minute quiz.
