Race guides, training frameworks, and gear comparisons, written for runners who want to run smarter and go further.
Most 100-mile DNFs come from execution errors, not fitness deficits. Concrete targets for effort, carbohydrate intake (60–90g/hr), sodium (500–1,000mg/hr), and when to drink — based on Hearris et al. 2025, Tiller and Millet 2025, and Noakes.
