Tapering: The Final 14 Days Before Your Race

The final two weeks before a race do not decide how fit you are — they decide how much of your fitness you can actually access on the start line. Tapering is the deliberate shedding of training fatigue, and depending on your starting point it can deliver two to four percent of performance. That is more than many a training week will ever give you.

Cut the volume — by 40 to 60 percent

The central lever is volume: gradually reduce your weekly training volume to 40–60% of its normal level. Ten hours become four to six. Meta-analyses on tapering (among others Bosquet et al.) show that a reduction of this magnitude over roughly two weeks produces the best results — clearly better than complete rest or an overly cautious reduction.

Important: the reduction comes from shorter sessions, not from dropping training days altogether. Your usual frequency (e.g. five sessions per week) stays largely intact; each session simply becomes considerably shorter.

Keep the intensity

The most common misconception about tapering: “I'm resting, so I only run slowly.” The opposite is true. Short, sharp efforts at race pace — for example 5 × 3 minutes or a few strides — keep neuromuscular tension and your feel for pace alive without building new fatigue. Rule of thumb: intensity stays, volume drops. Anyone who merely plods along for two weeks arrives at the start feeling “flat” and sluggish.

Sleep and carbohydrates

• Sleep: recovery happens during sleep — during the taper, eight hours or more are not a luxury but part of the plan. A sleep deficit in race week can hardly be repaid; the night before the night before the race counts more than the last night itself.
• Carbohydrates: in the last 36–48 hours before the race, increase carbohydrate intake to 8–10 g per kilogram of body weight. Thanks to the reduced volume and full intake, glycogen stores load above their normal level (supercompensation).
• No experiments: new foods, new gels, new shoes — none of that belongs in the last 14 days. Everything you use in the race has been tested in training beforehand.

Example week: the final 7 days before a marathon

• Monday: 40 min easy + 4 strides of 20 seconds. Easy, easy.
• Tuesday: 30 min with 3 × 3 min at marathon pace — the last sharp effort.
• Wednesday: rest day or a 20-minute walk.
• Thursday: 30 min easy + 3 strides. Keeps your running form awake.
• Friday: rest day. Increase carbohydrate intake.
• Saturday: 15–20 min very easy, 2 strides. “Open up” the legs without tiring them.
• Sunday: race day. The freshness is there — trust the plan.

The week adds up to perhaps 2.5 hours — from a baseline of 8 hours, that is exactly the desired 30–40%.

Common mistakes

• Tapering too short. Three easy days are not enough to shed weeks of fatigue. For marathons and gran fondos, 10–14 days are standard; shorter races need about 7.
• A “final workout” that is too hard. Repeating the long run in full length two weeks out “just to be safe” — a classic fatigue import at exactly the moment it hurts the most.
• Panic miles. The feeling of “I'm literally getting unfit” leads to extra sessions. That feeling is normal and is called the taper blues — it is a sign that the body is recovering, not deteriorating.
• Filling the free time with stress. The hours you gain belong to recovery, not to renovating the flat.

How Peakora plans your taper automatically

Tapering is firmly embedded in the Peakora engine's periodisation: the final two weeks before your A-race are built in as a dedicated phase — volume drops as planned, short race-pace efforts are retained, and race week opens with short leg-opener sessions so that you line up fresh but not “rusty”. Because the recovery monitor tracks your form (TSB) in parallel, you can see in black and white how fatigue falls and freshness rises — taking the sting out of the taper blues.
