WHY WE MOVE

Global talks.
Local steps.

Climate happens everywhere.

COP31 brings international climate negotiations to Antalya, Türkiye. Three One Tree Run brings the conversation to our streets, parks and coastlines. You don’t need a conference badge to take part.

Movement is for everyone.

There’s no qualifying time and no single way to join. Choose a movement that works for your body, your surroundings and your day. Go solo, bring a friend, or gather your club.

A small action. A shared signal.

Get outside, reconnect with nature, and add your city to a shared map. Together, we make the people behind climate action visible.

ONE PLANET. MANY STARTING LINES.

Put your city on the map.

One verified runner per country. If they are also the first participant, those recognitions are combined.

First non-runner +

The first verified walk, ride, roll, swim, skate or dance, from any country.

All shoutouts are subject to organiser verification. Nominated organisations must have a public website or social profile and be non-commercial and non-partisan. Registration alone does not guarantee recognition.
