Lactic Acid Junkies

An urban running crew where every pace is welcome and every kilometre matters. Come as you are. Leave stronger.

Who We Are

About the Crew

Lactic Acid Junkies Running Crew was born on the pavement — no fancy track, no membership fees, just people who love to run and the city they run through.

We started as a handful of friends chasing kilometres. Now we're hundreds strong, spanning every age, pace, and background across dozens of countries. Fast or slow, first timer or veteran — if you lace up, you belong here.

We run together, sweat together, and celebrate every finish together. That's the LAJ way.

Mission Statement

We Run So Everyone Can

Our mission is to build an inclusive, street-level running community that breaks down barriers — physical, social, and mental. We believe running is for everybody. We show up, we push each other, and we leave no one behind. The road is long. We run it together.
