Is This Program Right for You?
This 12-week base-building plan develops the aerobic durability, strength and trail skills needed before entering a race-specific 60K / 35 Mile Ultra build. It is a preparation period rather than a race plan and does not include a race taper.
What to Expect
• Easy and long runs that develop aerobic endurance
• Trail-specific climbing, descending and strength work
• Controlled tempo and threshold sessions that support running economy
• Planned lighter weeks balancing training load and recovery
• Progressive base development without race-specific tapering
• Clear HR- and TSS-based guidance for practical tracking
Coaching and Support
Every workout includes its purpose, intensity guidance and execution details. For support with program setup, training zones or TrainingPeaks, contact GA Endurance at coachsupport@gaendurance.com.
Starting Requirements
• Comfortably complete a 3–4 hour trail run
• Train consistently at least 5 days per week
• Have strong climbing, descending and long-run experience
• Use a tested fueling, equipment and recovery routine
A GPS watch and heart-rate monitor are recommended.
Final Note
Use this period to build a durable foundation before selecting a race-specific plan.
