Be a Better Runner Half Marathon – Sally Edwards

About the plan

A 10-week half marathon plan based on Sally Edwards' methodology, with a periodized structure in 8 distinct phases — the most detailed among the plans in the Be a Better Runner series. This program stands out for its granular periodization: after the base and endurance phase, it includes an active recovery week (week 5) before moving on to the strength, speed, power and peak phases. This structure allows the adaptations to be absorbed and prepares you for the plan's most intense blocks. Threshold work grows progressively longer, reaching 11 miles (18 km) at threshold pace in the peak phase.
