strawberry lifespan question

So I know a strawberry plants life cycle is about 5 years. Is that the individual single plant, not include the ones sprung off from the runners, or is that the plant and runner plants as a whole.

My friend just gave me some runners, new growth from last year. Her plants are about 4 years old. Does that mean this one is 1 year old or 4 years old?
Thanks

Strawberry runners are new plants. Many farmers will cut those runners into new rows to renew the process.
