Marathon 3-Week Taper Plan: Complete Mileage Schedule

The marathon is one of the endurance events where the taper period matters most—done right, it can shave 5–10 minutes off your time; done wrong, you might even hit the wall. Below are two versions of a concrete schedule.

Version A: Advanced Runners (Peak Week 90K, Goal Sub-3:30)

Week -3 (Total 65K, Down 28%)

Week -2 (Total 50K, Down 44%)

Week -1 (Total 30K, Down 67%)

Version B: Intermediate Runners (Peak Week 70K, Goal Sub-4:00)

Week -3 (Total 50K)

• Mon Rest, Tue 8K (incl. 3×1K T), Wed 8K E, Thu 10K (incl. 6K MP), Fri 6K E, Sat Rest, Sun 18K

Week -2 (Total 38K)

• Mon Rest, Tue 8K (incl. 2×1K T), Wed 6K E, Thu 8K (incl. 4K MP), Fri 4K E, Sat Rest, Sun 12K

Week -1 (Total 22K)

• Mon Rest, Tue 6K (incl. 4×400m), Wed 4K E, Thu 5K (incl. 2K MP), Fri 3K E, Sat 3K (leg opener), Sun Race Day

Pace Codes

Key Principles

1. Keep intensity stimulus until 6 days before the race (last T-pace session)
2. Keep MP blocks until 9 days before the race (let your body remember race pace)
3. Only run leg openers in the final 3 days before the race (short distance + strides)
4. Run 0 or 3K easy on the day before the race (personal preference)

Conclusion

The schedule is fixed, but your body is not—if you catch a cold or sleep poorly on any given day, take a rest day. But try not to skip the intensity blocks (T-pace, MP); they are the soul of the taper.
