The Taper Myth: Less Isn't Always More
Why most athletes botch their taper — and the simple framework I use with every athlete to arrive sharp instead of flat.
Taper is the most misunderstood phase of training. Too much rest and you arrive at the start line flat, sluggish, and detuned. Too little and you're racing on tired legs. Both kill the race.
The principle: cut volume, keep intensity
Reduce total weekly hours by 30–50% over 2–3 weeks. Keep the quality sessions — just shorter. A few sharp efforts at race pace remind the body what it's about to do. The fitness is already in the bank; taper is about removing fatigue without losing sharpness.
A 3-week marathon taper
- 01Week -3: 80% of peak volume, full intensity sessions
- 02Week -2: 60% of peak volume, intensity sessions trimmed to 70% duration
- 03Race week: 40–50% of peak volume, two short sharp efforts (e.g. 4×400m at goal pace)
Sleep is the real performance enhancer in taper week. Add 30–60 minutes per night. Everything else is secondary.
The behavioral trap
Tapering athletes panic. They feel sluggish on easy runs (normal — your body is shedding fatigue), then add extra sessions to chase the feeling back. Don't. That sluggish feeling is the adaptation working. Trust it.
What to actually do
- Sleep 30–60 minutes more per night
- Hydrate aggressively, especially 48 hours out
- Eat slightly above maintenance — top off glycogen
- Limit alcohol, big new meals, and long walks the day before
- Pack and rehearse race-morning logistics by Wednesday
