We wanted to remember how it felt and what worked.
We’re Kayleigh and Chris — Those 2 Runners on YouTube. Two normal runners who take it seriously. Runflect is the private diary we couldn’t find, so we built it.
We’re Kayleigh and Chris — Those 2 Runners on YouTube. Two normal runners who take it seriously, work hard, and want to be the best runners we can be. Runflect is the private diary we went looking for and couldn’t find. So we built it.

Every app remembers how fast. We wanted to remember how it felt.
Our watches and running apps kept everything: splits, heart rate, cadence, years of it. But when a run went well, or quietly fell apart, the numbers couldn’t tell us why.
Were we tired going in? Was it the bad night’s sleep? Where did it get hard in our heads — and what got us through it?
Were we tired going in? Was it the bad night’s sleep, the busy week at work, the new shoes? Where did it get hard in our heads — and what got us through it? That’s the half we care about most: when you’re fresh and when you’re flat, where you’re struggling mentally, and where you’re slowly getting stronger.
It’s the part of running almost nobody keeps a record of — and it’s usually the part that explains the rest.
Your runs arrive
From Strava, Garmin or Coros, with all your stats there. On their own, they’re just numbers.
You say how it felt
One tap, from Wrecked to Effortless — and the week takes on its colour.
In your own words
A line while it’s still fresh. Typed, or said out loud on the walk home.
And whatever else mattered
The weather, a tag, the shoes. All of it there when you look back.


















Real Runflect screens, filled in by an invented runner.
We looked everywhere for it. Then we built it.
- First
A notebook
Lovely to write in. Impossible to search, and never to hand when we wanted to look back at last spring.
PrivateSearchableNext to your runs - Then
A spreadsheet
Searchable, but cold. Nobody wants to fill in cell F42 after a session that nearly broke them.
SearchableFelt like a diary - Then
The running apps
Fantastic for sharing your runs and cheering each other on. But we wanted something private, just for us, and set up to be a diary.

We built Runflect
A diary that brings in your runs, then asks how each one felt — private, and easy to look back on.
A diary that brings in your runs from Strava, Garmin or Coros, then asks the one thing they can’t: how did that feel? Your feeling, your words and anything else that mattered sit right beside the numbers — easy to search, easy to look back on, and private.
PrivateSearchableNext to your runsFelt like a diary
The splits are the record. How it felt is the story.
The idea it’s built on
Private, so you can be honest with yourself.
Your diary is private. Nothing is posted and nothing is public. So write the bad days down exactly as they were.
Your diary is private. Nothing is posted and nothing is public. So write the bad days down exactly as they were — the doubt, the wobble at 25k, the session you skipped and why.
It works alongside Strava, not instead of it: your runs come across on their own.
It isn’t here to replace Strava. Keep that for sharing — your runs come across from it on their own, with every stat intact. Runflect is where you write the part you’d never post: for your own benefit, instead of in a notebook, and all organised for you.
Records the run.

Our diaries have shown us what a bad night really costs, and how far we’ve both come. We built Runflect so any runner can have the same.
Our own diaries have shown us things we’d never have spotted — what a bad night really costs, which sessions we dread for no reason, and how far we’ve both come.
We built Runflect for any runner who wants that too, whatever your pace and whatever you’re training for. We hope your diary does the same for you.
Keep on running.
