Negative visualisation: rehearsing the worst-case scenario so nothing surprises you on race day. Race morning: your rehearsed breakfast, Taper week: stay mobile, stay active, stop the strength work now. Fuelling: why your carb intake on Friday and Saturday is the most important nutrition decision of your week, and why eating carbs in the evening supports sleep.
