Half marathon
A 12-week half marathon training plan.
Twelve weeks works for both first-timers with a base and improvers chasing a personal best.
Base (weeks 1–4)
Easy mileage with one long run and a tempo.
Build (weeks 5–9)
Long runs reach 17–18 km, threshold reps to 5 × 1 km.
Taper (weeks 10–12)
Shorter long runs, sharper intervals, race week easy.
