Plan objective: 1) Build fitness with gradual progressions of volume and higher intensity training. 2) Prepare for an "A" race marathon. 3) Test periodically through the plan to a) assess for progression in the runner's FTP/CP estimate, b) provide updates to FTP/CP if environmental conditions change, c) optimize a multi-parameter power-duration curve (like WKO, Golden Cheetah, Stryd, and others), d) optimize the race power planning, whether it be by the SuperPower Calculator, the Stryd race ...
