Contribute data

Help build the evidence for everyday runners.

The evidence only exists because runners share their journeys. Every activity you contribute makes the picture clearer — for you, and for everyone who runs like you.

This is the quiet engine behind "Find Where You Fit." Not just a product feature — a shared resource, built together, given back to the people who created it.

Why it matters

Evidence gets sharper with every journey.

One runner's history is a story. Millions of them, observed together, become evidence — the patterns that quietly repeat across everyday running. You can only see where you fit because others chose to contribute first.

Bigger cohorts, truer fit

More journeys mean tighter, more meaningful communities — so the group you belong with actually looks like you.

Stronger evidence

Patterns drawn from more runners are more reliable, and they cover more kinds of people — beginners, comeback runners, every pace.

Given back, free

The evidence you help create is open to read. Contributing isn't a transaction — it's adding to a resource everyone shares.

The evidence network

Every athlete makes it smarter.

Your journey joins millions of others. Together they reveal what consistently appears across everyday running — and everyone benefits from the evidence, not just the people who can afford a coach.

What we use

The data behind the evidence.

Plain and specific — the running you've already done, nothing more. You choose what to connect, and you can stop sharing at any time.

Your activities

Runs you've recorded — distance, pace, date and route summary — from the sources you connect.

You choose the sources

Your race results

Public results like parkrun and race finishes that help place your journey in context.

Mostly already public

Your journey shape

How your running has changed over time — the trend, not the personal detail.

Aggregated, not identifying
How privacy works

Your data, on your terms.

Contributing should feel safe, not like signing away your life. Here's exactly how we treat what you share — in four straight lines.

Aggregated and anonymised

Evidence is built from thousands of runners at once. No chart, study or cohort ever identifies an individual.

You choose what to share

Connect the sources you want, leave out the ones you don't. Nothing is taken without your say-so.

Disconnect anytime

Change your mind whenever you like. Disconnect a source and it stops contributing — no friction, no penalty.

Personal in, aggregate out

We do not sell personal information, identifiable athlete records, or individual running histories. Aggregated and anonymised evidence may be published, shared, licensed, or commercialised as studies, benchmarks, reports, and population-level insights.

The compounding effect

The more runners, the better it gets.

As contributions grow, cohorts get more precise and studies cover more kinds of runner. This is the same chart we watch internally — confidence rising as the network does.

It's why contributing is the most generous thing you can do here. You're not just finding your own place — you're making the next runner's place easier to find.
