Stroller Pace Adjuster
See roughly how much a running stroller slows you down, from your flat solo pace and the combined stroller-plus-child weight.
Expected stroller-running pace
Pushing a running stroller adds effort, so expect to run a little slower — roughly 3–7% depending on the combined load. This is a rough heuristic: hills, stroller type, and whether you push one- or two-handed all change the real cost, so treat the number as a starting point and run by effort.
Running with a passenger
A jogging stroller turns a solo run into a two-person job: you’re carrying momentum, steering, and pushing extra weight, so the same effort produces a slower pace. Knowing the likely gap keeps you from feeling like you’ve lost fitness on days you’re on stroller duty.
The heavier the load, the bigger the penalty — which is why the adjustment grows with combined weight. Use it to set a fair expectation, then let effort, not the watch, decide how hard the run feels.
Frequently Asked Questions
How much slower is running with a stroller?
For most runners, pushing a running stroller costs a few percent of pace — commonly in the 3–7% range depending on the combined weight of the stroller and child. This tool scales the penalty with the load and applies it to your flat solo pace.
How is the adjustment calculated?
It starts at roughly 3% for a light load (around 10 kg combined) and adds about 0.2% for each additional kilogram, capped near 7%. That percentage is then applied to the solo pace you enter to give an expected stroller pace and the seconds added per kilometre.
Why is it only an estimate?
Real effort depends on things a single number can't capture: hills, headwind, stroller design and tyre pressure, the running surface, and whether you push with one hand or two. Treat the result as a starting point and run by feel — effort, not pace, should lead when you're pushing.
Do I need a special stroller to run?
Yes. Running with a stroller should be done with a purpose-built jogging stroller that has a fixed or lockable front wheel, a hand brake, and a wrist strap — everyday strollers aren't built for running speeds. Follow the manufacturer's minimum age guidance for the child, too.
Is running behind a stroller good training?
It can be. The added resistance and the slightly altered arm swing make it a solid strength-endurance session, and it lets you train when childcare isn't an option. Keep the effort easy on most stroller runs and save hard efforts for when you're running unencumbered.
Estimates and heuristics for general information — not medical or professional fitness advice. Use a purpose-built jogging stroller and follow its age guidance. If you are returning to running after pregnancy, get medical clearance from your doctor or a pelvic-health professional first.
