Tapering is hard. It often triggers a range of psychological anxieties and mental discomforts for runners. Things like phantom pains, fear of losing fitness, feeling sluggish or heavy, restlessness, irritability. Needless to say it sucks for most runners. BUT that doesn’t make it okay to skip 😬
Studies (including meta-analyses on endurance athletes) show these changes lead to real performance gains. Typically around 2–3% improvement on average, which can translate to minutes off a marathon time.
1. Replenishes glycogen stores: Your muscles and liver restock carbohydrates (your primary fuel for endurance efforts), helping prevent “bonking” and improving energy availability.
2. Repairs muscle tissue and reduces inflammation: Micro-tears and fatigue from hard sessions heal, restoring muscle power, strength, and freshness.
3. Boosts muscle glycogen and blood volume: This enhances oxygen delivery (via increased red blood cells/hemoglobin) and overall endurance capacity.
4. Improves running economy and efficiency: Your body uses oxygen more effectively at a given pace, so you feel smoother and less taxed.
5. Reduces fatigue and restores hormonal balance: Lower cortisol (stress hormone) and better testosterone/cortisol ratios improve strength, power, and anti-fatigue ability.
6. Strengthens immune function — Heavy training can suppress immunity; tapering lowers sickness risk right before race day.
7. Provides mental refreshment: Reduced load eases mental fatigue from training load and sharpening focus for race day.
We know it sucks, but it pays off. Do you also hate the taper phase?
