To effectively taper before a big race, you’ll need to strategically reduce your training volume while maintaining intensity. Start 1-3 weeks before race day, depending on race distance, with a 20-30% weekly mileage reduction. Keep 70-90% of your peak intensity through shorter, high-quality workouts, and prioritize recovery with adequate sleep and nutrition. Combine active recovery days with complete rest, and practice mental preparation techniques. The right taper approach can boost your performance by up to 3%.
