Your Adventure Begins Here

The Her Trails 100km Endurance Build is a 20-week, holistic training journey designed to prepare women for the physical demands, mental load, and long hours required to complete a 100km trail ultra.

This program blends endurance running, strength and mobility training, and intelligent recovery to help you arrive at the start line prepared, grounded, and capable of thriving on challenging terrain, not just surviving it.

What makes Her Trails different

  • We train the whole runner. You’ll build aerobic endurance and climbing strength, while also learning how to support your nervous system, recover well, and train in a way that respects your physiology and life load.
  • We prioritise durability over burnout. Long runs, strength, and recovery are layered deliberately so your body can absorb the work, not break under it.
  • We coach for real lives. Designed for women balancing training with work, family, and responsibility, with clear intent, simple weekly rhythm, and built-in flexibility.
  • We value calm, confident preparation. This isn’t about doing more. It’s about doing what matters, consistently and well.

Is this program right for you?

Training for 100km requires commitment, patience, and respect for the process. This program is designed to support women who are ready to train consistently, listen to their bodies, and build endurance over time.

This program is a great fit if you:

  • Are preparing for your first 100km, or returning to the distance
  • Have experience with trail running or shorter ultras (30–70km)
  • Can commit to consistent weekly training over 20 weeks
  • Value durability, recovery, and long-term health
  • Want clear structure without being micromanaged

This program may not be the right fit if you:

  • Are brand new to running or trail environments
  • Are currently managing an unresolved injury
  • Prefer highly prescriptive, day-by-day coaching feedback
  • Are looking for a short-term or low-commitment plan
  • Want a “more is better” or high-volume-at-all-costs approach
