    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 · Mar 21, 2027 – Apr 10, 2027

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