UTMB Kosci 50km - 20 weeks (upfront payment)

What to Expect for our program?

The Kosci 50 course is a unique blend of runnable trail, alpine exposure and altitude, and it requires smart, grounded preparation.

This 20-week program is built to meet the physical and mental demands of Kosci 50, while supporting you through strength, recovery, coaching and community.

You can access the Kosci 50 program in one of three ways:

  • As part of the All In Membership: Full access to this program and every other Her Trails experience, with year-round coaching and support.
  • As a discounted one-time purchase: Pay upfront and receive the complete 20-week program at a reduced rate. (which is where you have landed!!)
  • Via three monthly instalments: Spread your investment over three months, with immediate access to all program features. 

However you join, you'll receive the full Kosci 50 experience: including structured run sessions designed for the course, weekly education videos, live coaching, strength for runners workouts, mobility sessions, and access to a supportive training community.

What You’ll Receive:

  • 4–6 structured run sessions per week: progressive, terrain-specific, and aligned with the Kosci 50 course profile. Build your endurance, adapt to elevation, and develop the mental resilience needed for ultra distance.
  • Weekly education videos: race-specific insights and mindset tools, delivered weekly by our coaching team.
  • Live weekly coaching calls: connect with Coach Sam and the team to troubleshoot, reflect and stay grounded throughout the journey.

  • Private community space : connect with others preparing for events at Kosci in a shared space for encouragement, learning and accountability.

What Makes Her Trails Different?

  • We train the whole runner: Beyond the physical sessions, we support your nervous system, menstrual cycle, and what truly matters to you.
  • We coach in real time: Weekly live calls create space to reflect, ask questions and move through any blocks or doubts.
  • We are built by and for women: Every Her Trails program is grounded in female physiology, psychology and lived experience.

What People Are Saying:

“After five years away from running due to injury, I honestly didn’t know if I’d find my way back. Following the Her Trails 50km program has given me the structure and support I didn’t realise I was missing. I’ve built consistency week by week: slowly, sustainably, and it’s made me stronger and more confident, both on and off the trails. But it’s more than just fitness. This program has reignited something I thought I’d lost: a sense of belonging. The Her Trails community reminded me what it feels like to be seen, supported, and inspired. I’m running ultras again. I’m making new connections. And I’m doing it with joy. That’s something I didn’t think I’d say again.”
