Is How Fast You Walk More Important Than How Far?

By Kim Fisher · October 2026 · 6 min read

405,981 adults. The brisk walkers carried cells that looked years younger...

and the total amount they walked barely changed it.

The part almost nobody mentions is what that same pace may do for the ache you woke up with.

Gravel under my sneakers. Hills in the distance. One hand tucked in my vest pocket. These days I don't finish a walk asking how far I went. I ask how I walked.

What did the research find?

Researchers at the University of Leicester looked at 405,981 adults in the UK Biobank. People who described their usual pace as steady or brisk had longer telomeres than slow walkers. Telomeres are the protective caps on your chromosomes, and their length is used as a marker of biological age.

Here's the surprising part. When the team checked wrist-worn activity trackers, telomere length tracked with how intense people's everyday movement was, not with the total amount. A genetic analysis also suggested that the pace was driving the telomeres, not the other way around. The researchers estimated that a lifetime of brisk walking could mean a biological age up to 16 years younger by midlife.

Can walking help the ache and the mood?

Often. A Cochrane review of 44 trials found exercise cut knee arthritis pain by about 12 points out of 100.

And a 2025 review of 21 trials with 2,020 women in and after menopause found physical activity eased depression and anxiety, with low to moderate intensity enough.

The honest fine print

The telomere study relied on people describing their own pace, and a telomere is a marker, not a promise. The knee review covers women and men with arthritis, not menopause aches specifically. So we say "went with" and "helped," never "cures." Your own body gets the final vote.

The reframe

You don't need more miles. You need a few minutes that change your breath.

How fast is brisk?

About 100 steps a minute. A review of 38 studies landed on that number as the doorway to moderate intensity for adults. Count your steps for 15 seconds and multiply by four. Twenty-five steps in 15 seconds puts you right there. If 100 feels easy, nudge toward 110.

My walking pace test

I like to walk at a pace where I can hold a conversation, yet I can't sing a song. That's my sweet spot, and it's the one I teach.

What does a four-week brisk-walking plan look like?

Five easy minutes to warm up, five to cool down. The minutes below are the brisk part, at 100 steps a minute or more... a pace where you can talk and can't quite sing.

Week four adds up to 150 brisk minutes, the low end of the 150 to 300 minutes a week of moderate activity the Physical Activity Guidelines for Americans recommend. If a week feels like too much, repeat it. You set the pace of the plan, not the other way around.

I am strong, I am steady, I am still becoming. I walk with purpose, with breath, with grace. Today I let my pace speak louder than my distance.

Frequently asked questions

Is it better to walk faster or walk longer after 50?

Both count. The research suggests pace carries more weight than people expect. In 405,981 adults, brisk walkers had longer telomeres, and it tracked with intensity rather than total activity.

How many steps per minute is brisk walking?

About 100 steps a minute is the research marker for moderate intensity. Count for 15 seconds and multiply by four. If it feels easy, aim for 110.

Can walking help menopause aches and joint pain?

It often helps. Across 44 trials, exercise reduced knee arthritis pain by about 12 points out of 100. Those trials weren't menopause-specific, so rate your ache before and after a brisk walk and see what your body tells you.

How many minutes of brisk walking do I need a week?

The Physical Activity Guidelines for Americans recommend 150 to 300 minutes a week of moderate activity, and brisk walking counts. That is 30 minutes, five days a week. Building from 10 minutes over four weeks gets you there gently.
