Race to Zero is an ultralight packable system built for running 5km or 5 days straight.

There are some very simple rules of running. Rule one: lighter is nearly always better. Weight is the enemy – whether it’s your body or your kit. It’s the enemy of going fast. It’s the enemy of going long. And it’s the enemy of running like you ran when you were a kid. Your gear should feel weightless. So we’re building the lightest running system in the world. The mission is to get as close to zero as we can on the weighing scales, so once you put it on you forget it’s there. Race to Zero is an ultralight and super minimalist system of running gear that works together whether you’re running 5km or for 5 days straight. Each piece is built with advanced materials, packs down into itself, and fits into the palm of your hand. And the entire system weighs just 600 grams. We’re starting with four pieces – a t shirt, shorts, jacket and puffer.
