12-Week Strength for Half Marathon Running

This progressive 12-week programme is designed for adults aged 18–60 who can already run around 10K continuously and want to prepare confidently for a half marathon. It combines two focused strength sessions with easy running, quality running and a weekly long run to build aerobic endurance, sustained pace, running-specific strength and resilience. Training uses RPE so each runner can work at an appropriate level, with planned recovery weeks and a reduced load before a Week 12 half-marathon assessment or race.
