The science behind running your best marathon
Runners vary in how they prepare for a [[marathon]], but effective programmes balance multiple training intensities and individual needs. The article explains why the weekly [[long run]] is central for endurance, fuelling practice and resilience, yet suggests peaking long distances earlier in a plan rather than immediately before race day to allow recovery and refinement. It outlines key intensity zones — easy runs for volume, threshold work to raise the [[lactate threshold]] and tempo tolerance, and speedwork to develop [[VO2 max]], running economy and neuromuscular strength — including maximal sprints and the ‘speed base’ concept from [[Steve Magness]]. It also covers periodisation phases (foundation, development, specificity and taper), practical hill sessions, judicious cross-training such as [[aqua running]] for injury management, progression of long runs, pacing and nutrition to optimise race performance.
