13-Week Beginner Marathon Training Plan
This 13-week half marathon plan looking to build up from completing a recent 5k or 10k distance and looking to tackle the half marathon distance or improve on a half they have already done.
We build up from ~2.5 hours to a peak of ~4h of running in the week if doing all 4 runs. If doing 3 runs it will be ~2h of running up to ~3.5hours of running total. Make sure you are doing ~2h of running across 3x runs per week before starting this plan
You’ll run 3-4 days per week, typically including a long run, a threshold or half marathon-pace workout, a faster aerobic or speed-based session, and supporting easy runs to build durability and aerobic capacity. Training focuses on developing aerobic strength, improving marathon-specific efficiency, and sharpening pacing skills late in the cycle.
This plan is best suited for runners with a solid aerobic base who are comfortable running 2+ hours per week total . If you’re motivated, consistent, and ready to train with intent, this plan provides the framework to arrive on the start line fit, confident, and prepared to race.
My mission is to help athletes reach their potential through intelligent, sustainable training rooted in consistency, sound decision-making, and long-term development.
I coach athletes to think, not just follow. To understand effort, manage stress, fuel their work, and make good choices when it matters most. Performance is built by stacking consistent weeks, respecting the process, and adapting training to the athletes life demands.
