Build it around a crew near you
The plan gets better when a nearby run club meets on one of your run days. Pick your metro and the builder pins those crews to your training week — and finds a Half Marathon to point it at.

A Half Marathon build wants at least 8 weeks; less than that and the builder switches to a keep-ticking-over plan and suggests races with more room. These plans are general templates, not medical advice. Build up gradually and see a doctor before starting if you have any concerns.
