Supplements for Runners — Running Nutrition | 6AM Run

Five days out from the biggest race of your life, your legs feel like they're filled with wet cement. Your easy run yesterday felt harder than the 20-miler you crushed three weeks ago. There's a new pain in your shin that definitely wasn't there on Sunday. You're snapping at people you love. And a small voice in your head keeps whispering that you've already lost all your fitness.

Welcome to taper week. Every single one of those feelings is normal — and most of them are signs the taper is working exactly the way it's supposed to.

Why the Miles Drop 40–60%

A proper final-week taper cuts training volume by roughly 40 to 60 percent while keeping a little speed in the plan. That sounds dramatic until you understand what training actually is. Fitness is built in the hard weeks, but it's the easy days that let your body absorb it. Every long run and workout leaves behind microscopic muscle damage, depleted fuel stores, and accumulated stress. During peak training you never fully clear that debt — you run a little bit tired for months, on purpose.

The taper is when you finally pay it off. Muscle tissue repairs and comes back stronger. Glycogen stores refill to levels higher than you've carried all season. Stress hormones settle down. The fitness was built weeks ago; this week just removes the fatigue that was hiding it. Research on tapering consistently finds marathoners racing around 2 to 3 percent faster after a proper taper than without one. Over 26.2 miles, that's real minutes — earned by running less.

The Heavy Legs Are the Point

Here's the part nobody warns you about: fully stocked legs feel heavy. Every gram of stored glycogen holds onto roughly three grams of water, and a topped-off marathoner carries more stored fuel — and more fluid — than at any point in the training cycle. That fullness reads to your brain as sluggishness. Your legs aren't broken. They're loaded.

The flat feeling has a simpler cause: rhythm. For months your body ran on a steady drumbeat of mileage. Cut the volume in half and your legs lose the daily pop they're used to, like a singer who skipped the warm-up. That's why the week keeps short touches of race pace and a few relaxed strides — they keep the pathways between your brain and your legs awake without adding any fatigue. You're reminding your legs how to run fast, not training them to.

And no — you have not lost your fitness. Aerobic fitness built over months takes weeks of complete inactivity to meaningfully fade. Seven easy days don't erase it. They reveal it.

Phantom Pains and Taper Madness

The mystery ache that appeared from nowhere? The knee that twinges only when you think about it? During peak training you were too tired and too busy to catalog every sensation. Now you're rested, idle, and hyper-aware — and with a marathon looming, your brain is scanning your body like a smoke detector with fresh batteries. Nearly every marathoner reports phantom pains in taper week. Nearly all of them vanish at the start line, flooded out by adrenaline and actual work.

The irritability is real, too. You cut your mileage, which cuts your daily dose of the run itself, right as the nerves peak and the extra food starts to bloat you. You're climbing the walls because you have a race's worth of energy stored up with nowhere to put it. That's not a problem. That's the battery sitting at 100 percent. Save it for Sunday.

The Shakeout Run

The day before the race, run 15 to 20 minutes — painfully easy — and finish with four to six relaxed strides of about 20 seconds. That's it. The shakeout isn't training; it's a systems check. It burns off nervous energy, loosens the stiffness from travel and sitting, and reminds your legs what running feels like so the first mile on race morning isn't a shock. You should finish feeling like you could have run all day. If you finish tired, you ran it too hard. It should feel almost insultingly short.

Bank Your Sleep Early

Race-eve sleep is famously terrible — nerves, a strange bed, a 4 a.m. alarm. The good news: the night that matters most is two nights before the race, not the night before. So bank sleep early in the week. Get to bed an hour earlier from Monday on, nap if your body asks for it, and treat sleep like the final training block of the season — because it is. One rough night before the race, stacked on a week of good sleep, will not touch your performance.

What NOT to Do This Week

No new workouts — the fitness store is closed, and nothing you add now can help, only hurt. No making up missed miles; a run you skipped in September does not get rescheduled into race week. No new shoes, no new gear, no new breakfast, no adventurous restaurant the night before. Nothing new on race day starts in taper week. Stick to the exact routine you trained with — for me, that's the same pre-run ritual I've used all season, including my MARATHON before morning runs, because race week is the worst possible time to experiment. And skip the sightseeing marathon: hit the expo, grab your bib, get off your feet. Five hours of walking the city is a workout you didn't plan for.

The Mindset That Carries You to the Line

Here's the truth I come back to every taper: the hay is in the barn. The 5 a.m. alarms, the long runs in the rain, the workouts you didn't want to do and did anyway — that was the race. Sunday is the celebration lap where you go collect it. Your only job this week is to rest, eat, sleep, and trust work you've already proven you can do.

After the finish, the work flips to recovery — that's when something like FINISHLINE earns its place in my routine, and our first-7-days recovery guide walks through the whole post-race week. Want the full race-week logistics — the carb load, the race-morning timeline, all of it? It's laid out in our NYC Marathon race week plan and the taper week nutrition guide.

So tell me — what's your taper madness? The phantom shin pain, the wall-climbing, the dream where you oversleep and miss the start? Drop yours in the comments. Misery loves company, and we're all five days out together.
