Run with Mettle

mettle 

noun
A person’s ability to cope well with difficulties; someone who has spirit, courage and tenacity.

The story starts in the Chamonix mountains with one mission: to help runners like you break through your limitations and reach your greatest potential. Whether you want to run your first ultra; earn that 100-mile buckle; or train towards a personal adventure, we understand where you’re coming from, and will support you every step of the way.

Challenge

Mettle represents a dedication to continuous improvement by showing up, putting in the work, being healthy and having fun. Progress, not perfection. But make no mistake: this won’t always be easy. We will challenge you, every bit as deeply as we challenge ourselves, to do better than yesterday.

Community

Trail and ultra running is a solitary sport. We are proud of our global community where runners connect and share the journey. With a Chamonix HQ and a strong network of connections wired into the US trail and ultra scene, we’re a tight-knit community with an international outlook.

Celebration

We’re brimming with positivity because we have a lot to celebrate at Mettle. Our athletes results tell their own stories. As for us, we’re doing the very thing that we’re most passionate about, and that we know we do the best and love the most: empowering, supporting and educating runners like you, achieve your goals.

Dr Kaz Williams, UESCA Running Coach and Performance Psychologist. Striving to help people discover their mettle.

Hi, I’m Kaz. I founded Mettle to help you take on challenges you are curious about, whether that’s chasing a PB or a distance you aspire to run. Our purpose is to provide you with coaching plans, mental strategies and honest support to be the best trail and ultra runner you can be.

My trail running journey started in Chamonix, France with the Mont Blanc Marathon in 2010. I am crazy about running far on dirt, through forests, up mountains and by lakes. Favorite adventures include Tahoe 200, Moab 240, 1 loop at Barkley Marathons, Ouray 100, Across the Years (10 days), TDS (UTMB series) and Tot Dret, Italy. I have met incredible people during these races, shared priceless moments and experienced boundless kindness. I am grateful to be part of this amazing community.
