A marathon taper reduces weekly mileage by 25–40% over 2–3 weeks before race day, maintaining short race-pace segments while cutting volume so accumulated fatigue dissipates without losing fitness.
Who this is for
Marathon runners in the final 2–3 weeks of a training block who want to arrive fresh without feeling flat.
3-week taper model
| Weeks out | Volume reduction | Long run | Quality work |
|---|---|---|---|
| 3 | -20% | 12–14 mi | Short tempo |
| 2 | -35% | 8–10 mi | 6 mi w/ 3 mi @ MP |
| 1 (race) | -50% | 4–6 mi | 2–3 mi @ MP mid-week |
What to keep during taper
Short race-pace touches (2–4 miles at marathon pace) maintain neuromuscular sharpness.
Sleep, hydration, and carbohydrate loading in the final 48–72 hours matter more than any last-minute long run.
Common mistakes
- Tapering too aggressively and feeling sluggish on race day.
- Not tapering at all — racing on accumulated fatigue.
- Trying a new shoe, gel, or breakfast on race morning.

Frequently asked questions
How long should a marathon taper be?
2–3 weeks for most runners. 3 weeks for high-mileage athletes.
Should I run during taper week?
Yes — reduce volume but keep legs moving with short easy runs and one race-pace session.
Why do I feel sluggish during taper?
Normal — legs store glycogen and absorb training. Trust the process.
What is marathon pace during taper?
Short segments (2–4 mi) at goal marathon pace, not full dress rehearsals.
