Your joyful running journal
Running apps turned running into a spreadsheet. ZenRun is a journal — Log your run in 2 seconds, build your rhythm and find joy in every step.
1 more run this week
Running has been hijacked by metrics.
Open any popular running app and you're hit with pace splits, cadence, heart rate zones, VO2 max estimates, power output, vertical oscillation. Then comes the social layer — leaderboards, segment records, and the unspoken pressure to perform for an audience.
Trying to track whether we are staying in optimum zone 2, pushing another mile to staying on top of leaderboard and often running the easy runs — the foundation of aerobic fitness — too fast because posting a slow pace feels embarrassing are taking the joy away from running.
What started as tools to help runners have become tools that own them. The run worth having, it turns out, is the one in which you are present — not to the data, but to yourself.
A different philosophy
ZenRun is built on ideas from runners and thinkers who understood something the fitness industry forgot.
“Sometimes, we complicate things with gadgets and gear, when what we really need is to trust our bodies and keep things simple.”
Christopher McDougall, Born to Run
The Tarahumara run hundreds of miles in thin sandals, smiling. No GPS. No heart rate monitors. They run because running is woven into their culture — a form of community and celebration.
“The only opponent you have to beat is yourself, the way you used to be.”
Haruki Murakami, What I Talk About When I Talk About Running
Murakami has run marathons for four decades. He doesn't run to live longer. He runs to live fully. What matters is whether you improved over yesterday — not where you rank on a leaderboard.
“It is only necessary that he runs and runs and sometimes suffers. Then one day he will wake up and discover that somewhere along the way he has begun to see order and law and love and Truth.”
George Sheehan, Running & Being
Running transforms the runner. Not through data, but through the accumulated experience of showing up, day after day.
Consistency is the only metric that matters.
The single most important factor in running progress is not pace, cadence, or VO2 max. Runners who show up regularly — even with imperfect sessions — build lasting fitness. Chasing perfect data slows you down.

How ZenRun works
Everything you need, nothing you don't.
Log in 2 seconds
Pick your distance, enter your time, done. You can use your Apple Watch or not. Run however you want, log it when you're back.
Rhythm rewards showing up
Run at least twice a week to keep your rhythm going. Not pace. Not distance. Just presence. And showing up.
100 milestones for your journey
Earn achievements across your running life — first 5K, 100th run, a year of consistency, and beyond. Your journey, celebrated.
Scenic run photos
Capture the joy of outdoor runs. Tag photos to distance markers. Build a visual album of your running journey, km by km.
Circles, not leaderboards
Share your running journey with up to 10 close friends. Accountability and maybe some joyful competition.
Goals that keep you honest
Set yearly and monthly km targets. A simple progress bar shows where you are and where you should be.
Just enough data
Distance. Time. Rhythm. Goals. Personal records. That's the full list. No cadence, no heart rate zones, no VO2 max.
Outdoor & treadmill
Log runs by type. Filter your stats and personal records by outdoor or treadmill to see what matters to you.
Edit anytime
Made a typo? Added the wrong distance? Edit or delete any run, anytime. Your log, your rules.
You are a ZenRunner if you...
- Run 2–5 times a week and want to keep doing that for years
- Value the running mindfulness as much as the physical fitness
- Have used tracking apps but have not stayed consistent
- Care more about running than chasing a PR every week
- Want to share your journey with close friends
- Believe that the best run is the one you actually did
We're not for the runner optimising their 5K time by 3 seconds. We're for the runner who just wants to run.
Built by a runner who keeps starting over.
I've started and stopped running more times than I can count. I ran consistently for a summer 3 years ago. Since then it has been on and off. Cold rainy London weather and too much at work, I hardly ran at all in 2025. Then, at the beginning of this year, I set a simple goal: run 1,000km this year. Not for a race. Just to see if the habit could finally stick.
I built ZenRun during the same period — alongside the runs, through the weeks of motivation and the weeks I nearly quit again. Every feature exists because I thought of it while I ran.
170km in, both the habit and the app are still going. ZenRun is a running journal built by a runner who's still journaling.
Early Access
We're building ZenRun in the open.
ZenRun is not a finished product — it's a running journal being built alongside its first users. Every feature is shaped by runners like you. Join early, share what's working, tell us what's not, and help shape what ZenRun becomes.
