“I was up before dawn to run before the heat became overwhelming. I had an elevation goal to achieve so I chose to run along Clay Cliffs.
It was tough.
It was early.
But it was totally worth it for the breathtaking views.”
- Nadia 🏃🏻‍♀️Our athlete, Nadia, sharing how getting up early for a long run works a treat, when you live in a very hot and humid country.It’s also great race day prep! It helps train your body and mind to get ready early in the morning for the adventure ahead.Thank you for sharing your long run and sunrise with us @nadia_portelli 🙏Here’s to an awesome week!Love and Mettle

Every challenge asks the same question: How will y

Every challenge asks the same question: How will you respond when it gets tough?Huge congratulations to Arseni for an incredible achievement - summiting Gran Paradiso, Italy at 4,065m on a ski tour last week.This kind of challenge isn’t just about physical fitness and endurance - although it demands plenty of that - it’s also about mental strength.“You can’t just say you want it. You have to work for it - physically and mentally.”
- ArseniFacing altitude, uncertain conditions, and hours of effort on skis, builds a resilience that directly transfers to trail running.Staying present, positive and the ability to adapt when things get tough is what sets great athletes apart and builds confidence for other challenges whether up a mountain or in life 🏔️Proud of you Arseni! 💪How will you respond when it gets tough?Love and Mettle,
Kaz x.
