Taper is the part of training that feels worst and works most. You've spent five months building volume; now you have to throw most of it away for three weeks. Your legs feel heavy. Your fitness feels like it's slipping. You start Googling "is it bad to do one more long run." (Yes.)
This is the whole guide: a working 3-week taper protocol for any ultra distance, plus the small-but-real psychological tools to manage taper madness.
Week 3 out — 60% of peak volume
Cut peak weekly mileage by 40%. The Saturday long run is 60–65% of your peak long run (so 18 mi if your peak was 28). Keep one quality session early in the week. Keep your back-to-back, but smaller. Strength work continues.
Sample week:
- Mon: rest + 20 min strength
- Tue: 5 × 3 min at threshold (last real workout)
- Wed: 6 mi easy
- Thu: 6 mi easy with strides
- Fri: rest
- Sat: 18 mi long
- Sun: 8 mi back-to-back, easy
Week 2 out — 40% of peak volume
Cut another 30%. Last real long run of the cycle (12–14 mi) on Saturday. No quality work; everything aerobic. Strength drops to one short session, mobility-focused.
- Mon: rest
- Tue: 5 mi with 3 strides at the end
- Wed: 5 mi easy
- Thu: rest or 3 mi shake-out
- Fri: rest
- Sat: 12 mi long, easy pace
- Sun: 4 mi recovery
Race week — 25% of peak volume
Last quality work was Tuesday of last week. This week is feel-good miles only. 4 mi Monday, 3 mi Wednesday, 2 mi Friday shake-out. Rest Thursday. Race Saturday.
- Mon: 4 mi easy
- Tue: rest
- Wed: 3 mi with 3 strides at the end
- Thu: rest
- Fri: 2 mi shake-out + strides
- Sat: race
The taper rules
1. Cut volume, not intensity. Every taper run should still hit at least one short fast effort (a few strides at the end). Pure-easy taper makes legs feel sluggish on race day. Brief, sharp efforts keep neuromuscular activation alive.
2. Don't try anything new. Not new shoes, not new gels, not new socks, not new music, not new routines. Race-day kit must be 100% identical to your peak training weeks.
3. More sleep, less wine. Add 30 min/night of sleep starting week 3 out. Stop drinking alcohol entirely 14 days before the race. Both make a measurable performance difference.
4. Carb-load is the LAST 48 hours, not the whole taper. Don't try to bulk-carb for 3 weeks; you'll just gain weight. Eat normally through week 1 and 2 of taper, then load aggressively (5–7 g carbs per kg body weight) Friday and Saturday before a Sunday race.
Taper madness — what's normal
During taper, you'll feel:
- Heavy-legged on every easy run
- Mildly anxious or irritable
- Phantom injuries that disappear within 48 hours
- Trouble sleeping the night before race day (the night before that night is what matters; sleep then)
- Convinced you've lost fitness
You haven't. Taper-madness is a signal that the protocol is working — your body is rebuilding itself before the race. The athletes who skip taper because they "feel bad" consistently underperform. The athletes who trust taper consistently PR.
The single most important taper rule
No "one more long run." The week-3-out long run is the last one. Your fitness is locked in by then. Anything you do after only depletes you. The runners who blow up at mile 60 of their 100 typically did one extra 22-miler "just to be safe" 10 days before the race.
Trust the taper. The work is done. Your job now is to show up rested.
One last thing for race week: the ultra race-day checklist covers everything that goes on you, in your vest, in each drop bag, and in the crew bin. Print it Tuesday of race week. Pack from it Wednesday. Sleep better Thursday.

Every pace, zone and power figure here needs something recording it. These three cover running, long days and the bike.
