    Aerobic foundation: mostly steady endurance work that grows the aerobic engine and the durability the later phases stand on.

  2. 02Build6 weeks · Dec 14, 2026 Jan 24, 2027

    Progressive overload: training load climbs in waves, with harder weeks stacked on the base and planned recovery weeks that let the gains land.

  3. 03Peak3 weeks · Jan 25, 2027 Feb 14, 2027

    The hardest weeks of the plan: race-specific intensity at nearly full training load, sharpening exactly what this race asks for.

    Volume drops while intensity stays: short, sharp efforts keep the legs awake as fatigue drains away.
