How does Couch to 5K work?
On this page
Three runs a week for about nine weeks. Week one alternates 1 minute of running with 90 seconds of walking, and each week you run a little more, until you can run for 30 minutes without stopping. Repeat any week that felt too hard, since the NHS says nine weeks or longer is fine.
Plenty of people decide they’re “not runners” on the first day they try. They head out, run a mile as fast as they can, can’t breathe by the end of the street and never go again. Couch to 5K works because the first runs are tiny. Sixty seconds of running is something almost anyone can finish, and finishing is what brings you back for the next one.
What we’d do
If running appeals to you, do the plan. Run the running parts slowly enough that you could still say a few words, and walk the walking parts briskly. Keep two strength sessions a week alongside it. Repeat a week whenever you need to. If you’d rather not run at all, the interval walk gives you the same on and off pattern at a walking pace.
It works like learning to swim in the shallow end. You stay where your feet touch the bottom until one day you don’t need to.
Where it came from
Couch to 5K was made by a new runner, Josh Clark, who wanted to get his mother, then in her fifties, off the couch and running too. A 5K is 3.1 miles. England’s National Health Service now publishes it for free, as an app with a coach in your headphones and as a week-by-week plan on its website. The NHS plan has you run three times a week with rest days in between, at whatever pace feels right, and says you can take nine weeks or longer.
How does it count toward the 150?
Running is vigorous activity on CDC’s list, and the US guideline counts every vigorous minute as two. Once you’re running 30 minutes three times a week, that’s 90 hard minutes, which count as 180 of the 150 a week. You’ll be past the cardio minimum on running alone. Add two strength sessions and you’ve covered both halves of the guideline.
In the early weeks, the running minutes count double if you can only say a few words while you run. The walking minutes count once if they’re brisk.
What if I don’t want to run?
Walk the same pattern. In a 2007 trial, 246 adults around 63 walked fast for 3 minutes and easy for 3 minutes, five times, on four or more days a week. After five months their thigh strength was up 13% and their walking fitness 9%. The interval walk in Today’s session plays that exact pattern, with a beat that speeds up and slows down.
How many calories does running burn?
More than walking the same distance, about half again as much once you take away what you’d burn sitting. tdee.guide’s page on calories in a mile walked or run has the numbers for your weight.
Should I check with a doctor first?
The NHS suggests seeing a doctor first if you’re worried about your health before you start. Talk to yours if you’ve had chest pain, dizziness or fainting with effort, or if you have a heart condition, kidney disease or diabetes and you’re not active now. Who should check with a doctor first has the full list.
