Plan Description


Structured Path to Your First Century


Transitioning to a 100-mile event requires a methodical approach to endurance and fatigue. This 16-week plan provides a professional framework to reach the distance with physical readiness and mental composure. We prioritize science-informed programming that builds capacity around a professional schedule.


The program focuses on gradual adaptation. By following a structured build, you remove the uncertainty of guessing volume. This ensures you develop necessary stamina without overtraining, allowing you to focus on the execution of the ride itself.

The Benefits



  • Endurance Readiness: A logical progression from 90 minutes to 80 miles builds the physiological foundation for 100 miles.

  • Fueling Strategy: Integrated nutrition guidance helps maintain energy levels during long-distance efforts.

  • Time Efficiency: Achieve results on three purposeful rides per week, fitting into a busy lifestyle.

  • Mental Composure: Arrive at the start knowing you have completed the specific work required for the distance.

16-Week Progression



  • Weeks 1 to 8: Foundation. Establish a consistent rhythm and build base endurance through gradual volume increases and threshold work.

  • Weeks 9 to 16: Specificity. Introduce preparation rides, peaking with an 80-mile effort followed by a taper to ensure you are fresh for event day.

The Efficiency Gap


Progress often stops in the "grey zone"—training that causes fatigue without specific adaptation. This plan gives every session a purpose: recovery, strength endurance, or base building. This maximizes the benefit of every hour on the bike and ensures training remains sustainable.

Is This For You?



  • The Century Aspirant: You currently ride for 90 minutes comfortably and want a direct, structured path to 100 miles.

  • The Busy Professional: You need a manageable schedule that delivers results within a real-world week.

  • The Goal-Driven Athlete: You are preparing for a specific event and want to be fully prepared for the physiological demands of the day.

Deliverables



  • 16 weeks of structured cycling workouts with zero filler miles.

  • 3 purposeful sessions per week: endurance, intervals, and recovery.

  • Coach support via email for guidance on session adjustments.

  • Device Sync: Sessions load directly to your bike computer for real-time guidance.
