GPT 100 Miler Solo: 20 Week Her Trails Training Program

Ready to take on the GPT 100 Miler (Solo)? This program has been built specifically for the demands of this extraordinary event: over 7,000m of climbing, technical terrain, and the mental test of moving through day and night in one of the most remote places on earth.

Designed in close collaboration with pioneering ultra runner and adventurer Ray Zahab, this 20-week comprehensive training block is more than your typical plan.  It’s a system to build the durability, mindset, and confidence you’ll need to thrive at GPT, and beyond.

To get started, you should already have a strong base: at least one 100km finish in the past 12 months, weekly mileage of 60km+, and long runs over 30km. From there, we’ll take you step by step into the world of 100 miles.

How We Program at Her Trails

At Her Trails, we honour the complexity of the female experience. Our programs combine physiology, mindset, progressive loading, and real-life adaptability. Recovery isn’t reactive: it’s built in. Nutrition, breath, and mobility are performance tools, not afterthoughts.

  • Establish: Build rhythm, breath, and foundational strength.
  • Build: Expand capacity, develop terrain skills, deepen fuelling practice.
  • Strengthen: Stress-test durability with climbs, descents, and back-to-backs.
  • Sharpen: Drop volume, keep race-specific sharpness + clarity.
  • Peak & Taper: Rehearse, restore, and reinforce belief.
What Makes This Program Different:
  • Race-specific: Long climbs, technical descents, back-to-back long runs, pole integration, and gear simulation from the early weeks.
  • Female-focused: Training respects cycle health, iron status, joint stress, and energy shifts.
  • Ray Zahab’s insights: From posture, nasal breathing and mindset to fuelling protocols that hold steady even when you are 30 hours in.
  • Community + coaching: Weekly live calls and daily online support keep you connected and accountable.
  • Whole runner approach: Strength, yoga, mobility, breath-work, and nervous system care are integrated, not optional.
What You’ll Receive:
  • 4–6 structured run sessions per week tailored to GPT terrain & elevation.
  • 1–2 strength sessions weekly for climbing power and descent durability.
  • Mobility, yoga, and recovery practices to keep your body aligned and strong.
  • Back-to-back long runs to mimic race fatigue and refine fuelling.
  • Weekly live coaching + community calls.
  • Daily online community support + accountability.
  • Nutrition + fuelling guidance designed for ultra endurance demands.
  • Physio-led injury prevention and recovery strategies for female runners.

While designed specifically for the GPT 100 Miler, this program will also prepare athletes for other mountainous 100 milers such as UTMB, Hardrock, and Western States.
