Who are tr3?

tr3 -- pronounced “tee-are-3” -- is a platform created for serious runners, by serious runners.

We publish authentic, high-quality, science-backed content for recreational runners who care about performance, not just participation.

This is a space for the kind of runners who open Strava before they shower — not to justify dessert, but to chase growth; the kind of runners who want to understand why something works, not just be told what to do.

The name stems from the four equal stages that any serious runner should follow: train, race, recover, repeat.
