When to Stop Lifting Before Your Marathon
Show notes
What the episode covers
What's actually happening in your body during taper week, and when should lifters-turned-runners stop strength training before race day? This Tuesday's episode breaks down peak week, taper, and supercompensation, then tests whether the taper research holds up once a botched long run enters the picture.
Listeners will learn how detraining research explains a two-week strength window before real losses set in, why VO2max decline data argues against cutting load too soon, and why heavy legs and poor sleep during taper are normal physiology rather than warning signs. The episode closes with Hyrox's expanded 2026/27 calendar as a case for sequencing races instead of rushing one.
- How peak week, taper, and supercompensation actually work together
- A week-by-week plan for tapering strength training without losing fitness
- Why glycogen loading and race-pace strides matter more than panic workouts
Full Spectrum Fit treats endurance and strength training as one connected system, not competing disciplines.

Quick answers
Straight from the episode
The questions this one settles, without the listen.
- Does strength training help or hurt marathon taper?
- Amara cites RunnersConnect detraining research showing strength stays near baseline for about two weeks without training, with real losses appearing around week four. The advice is to keep load high but drop volume during taper rather than cutting strength work entirely.
- Is it normal to feel heavy-legged and sleep poorly during marathon taper?
- Yes. Amara explains these sensations are normal physiology during taper, not warning signs of lost fitness. Miles admits his own recurring taper-week panic about dead legs, and Amara reassures him it's expected.
- What does the research say about tapering before a marathon?
- Amara references a Frontiers study showing a disciplined taper produces a measurable time-saving benefit. Miles pushes back, arguing this benefit is often moot for amateurs who've already wrecked their fitness with botched long runs before the taper even starts.
- How should runners handle nutrition during taper week?
- Glycogen loading during taper needs to be intentional because appetite naturally drops along with training volume. Runners can't rely on hunger cues alone to fuel properly, so carb and protein intake should be planned rather than left to instinct.
- Should you fit in a Hyrox race during marathon taper?
- No. With Hyrox's expanded 2026/27 calendar offering 107 race weekends and about two million expected athletes, Amara argues the bigger schedule is a reason for patience, not urgency, so racers should sequence events rather than squeezing one into marathon taper.
- What happens to VO2max during a proper taper?
- Amara cites Mujika and Padilla's research on VO2max decline, cautioning that a common taper mistake is lightening training load too much, which can undercut the fitness benefits taper is meant to preserve.

MilesHey, everyone. Welcome back to Full Spectrum Fit. Amara, how'd training go this week?
AmaraHonestly, my hamstrings hate me. 16-mile Saturday and my pace fell off worse than I wanted.
MilesClassic lifter turned runner problem.
AmaraExactly.
MilesGood news, my easy runs actually felt smooth for once.
AmaraSame, once the soreness faded. Okay, switching gears. Fall marathon season is basically here.
MilesYeah, The5krunner published a piece on July 23rd pointing out there's still four marathon majors left on the 2026 calendar.
AmaraFour majors still to go? That's a packed fall.
MilesIt is, and that's got us thinking about taper season. Whats actually happening in your body when you back off before race day?
AmaraWere breaking down peak week, taper, and supercompensation, and Ive got questions about whether the taper research holds up once real training log damage enters the picture.
MilesHere we go again.
AmaraSomebodys got to keep you honest.
MilesFair. Were also tackling when lifters turned runners should actually stop lifting before race day.
AmaraBecause stop lifting a month out is bad advice.
MilesBad advice. Later, taper nutrition, why heavy legs during taper are normal, and Hyroxs expanded race calendar.
AmaraTwo million athletes are expected to compete this season apparently.
MilesTwo million. Alright, lets talk about what your legs are actually doing this week.
AmaraReady when you are.
MilesSo my left hip flexor is filing a formal complaint after Sundays long run.
AmaraHow long are we talking?
MilesEighteen miles. Felt strong through fifteen, then it just locked up.
AmaraClassic. Meanwhile, I deadlifted Tuesday and my hamstrings are still yelling at me in the shower.
MilesSee, this is why I keep saying lifting and marathon training don't always play nice.
AmaraThey can. You're just not warming up right.
MilesDebatable. Anyway, good week overall, just creaky.
AmaraSame creaky but on track, which, by the way, matters a lot right now.
MilesBecause the calendar just got loud.
AmaraGive me the dates.
MilesBerlin lands Sunday, September 27th, Chicago's October 11th, and New York's November 1st.
AmaraThat's not far off at all.
MilesRight? Depending which race you're running, you're somewhere between 8 and 13 weeks out. Today. Right now.
AmaraSo if you're one of our listeners who signed up. Signed up back in the spring feeling invincible.
MilesWelcome to the part where it gets real.
AmaraAccording to the 5K Runner's piece from July 23rd, four of the Abbott World Marathon Majors are still left this year with Tokyo, Boston, and London already done.
MilesAnd that spring block, by the way, was absurd, but that's a story for another day.
AmaraIs it, though? You clearly want to talk about it.
MilesFine—five seconds! The times coming out of London were the fastest we've ever seen.
AmaraOkay, noted, Filed, Moving on.
MilesSo, Sequel time: we did the Marathon Meets Leg Day episode back in May.
AmaraRight, all the fun stuff-Zone Two, Lifting, how to not hate your life.
MilesThis one's narrower: we're zooming into Peak Weeks and Taper because that's exactly where everyone listening sits right now.
Speaker 3Now.
AmaraWhich raises the actual question: when your legs feel like mine do today, is that Peaking working or is that just damage?
MilesThat's the debate. Let's find out which one of us is right. Building on that panic we just laughed about, let's talk about where people actually sit in the calendar right now.
AmaraOkay, so peak week. Everybody thinks it's just the hardest week, and then you coast into the finish. Wait for it. Not quite.
MilesRight, and I've seen this with athletes in my groups. Peak week is that final stress dose, but the taper is when the body actually caches in the fitness you built. That super compensation is real, but only if you set it up right.
AmaraExactly! Super compensation-fancy word, simple idea: you break the body down, back off the load, and boom, it rebounds stronger than before the stress.
MilesSounds like my fridge after Thanksgiving.
AmaraSure, if leftovers made you faster. But here's the scale of who's doing this taper right now:
MilesHit me.
AmaraPlot twist on the numbers here: New
Speaker 4-
AmaraNew York Road Runners reportedly pulled in over 240,000 draw applications for one race. Chicago drew north of 200,000 for around 53,000 finishing spots.
MilesWait, 200,000 applications for 53,000 spots?
AmaraYeah, most people reading this are literally tapering inside an incredibly crowded, incredibly anxious field right now.
MilesNo wonder I'm getting texts from runners at two a.m. asking if they should adjust their paces. Everyone's anxious, and rightfully so—the numbers are brutal.
AmaraAnd here's the research angle: Smyth and Lawlor, published in Frontiers in Sports and Active Living in twenty twenty-one, looked at roughly a hundred and fifty-eight thousand recreational runners.
MilesWhat would they find?
AmaraA disciplined three-week taper linked to a median f You can finish time saving near five and a half minutes compared to a minimal taper, and that's not nothing.
MilesIt's real, but I'll be direct. Most amateurs I've worked with never get a clean shot at that taper because they compromise it weeks before taper even starts. The damage is already done by week 15.
AmaraHow so?
MilesBecause they blow up the peak long run. I've reviewed hundreds of training logs and it's the same story. same story every time. Guys are hitting 20 miles two weeks out while they're already nursing something. An IT band, shin splints, hip flexor tightness.
AmaraExactly right. So the taper's irrelevant if the fitness underneath is already cracked. You can't fix September in October.
MilesPretty much the taper doesn't fix bad decisions made in week 14, it just reveals them.
AmaraBrutal, but fair.
MilesI had someone text me a few weeks back saying their taper felt absolutely wrecked. And when I looked back at their data, it wasn't the taper. It was that final long run they ran five seconds per mile too fast.
AmaraRight, so the study measures the average runner. It's not measuring the person who trashed their knee in September and never addressed it.
MilesExactly. Frontiers gives you the population number. Your training log gives you the truth.
AmaraTruth Fair split there—research on one side, actual bodies on the other.
MilesAnd once you know where you sit in that timeline, taper is easy to define but there's a bigger question hanging over it:
AmaraWhich is?
MilesWhat happens to the barbell during all this? Do you drop lifting the second taper starts or hold on to it?
AmaraOh, this is where it gets good—that's a fight for the next segment.
MilesBuilding on that, so when do people actually stop lifting? Not textbook, real world.
AmaraOkay, so get this, most runners bail four to eight weeks out, and I'm
MilesWatching it happen constantly in the training logs, that's a full month of maintenance torched for zero payoff on race day.
AmaraSeriously, a full month?
MilesA full month, I see the logs.
AmaraI see it too. Reviewing training logs, that's exactly what shows up. Week nine hits, everything aches, and the gym visits just stop.
MilesWhich is the wrong move. RunnersConnect summarized the detraining research. Strength holds close to baseline through about two weeks off; the real loss shows up closer to week four.
AmaraTwo weeks, huh?
MilesPitch twist, bail eight weeks out and you're literally detraining for six of those weeks for nothing!
AmaraHere's where I'm skeptical about that number. It's clean on paper, sure, but I've watched the actual logs: runner with dead legs staring down a squat rack in week nine. That's the math that matters.
MilesHere's the thing-feel and physiology aren't the same thing, but physiology is what shows up on the start line.
AmaraFine. Give me the actual week-by-week, then.
MilesTwo sessions through peak week-same loads you've used all summer. Taper week one-drop to one session, cut the volume hard-keep the weight.
AmaraKeep it, not lighten it?
MilesKeep it, and this is where it gets good. Mujika and Padilla's research, which the shift to strength taper guide cited, shows VO2max can actually drop four to six percent within two to four weeks of reduced training. Cut intensity along with volume and you lose ground on both fronts.
AmaraFour to six percent is nothing.
MilesIt's not, so the mistake isn't lifting less, it's going lighter and less. Yes, at the same time.
AmaraWalk me through the final stretch.
MilesTaper week two: one short session five or six days out, then stop.
AmaraNothing the last four or five days?
MilesNothing let the legs come back.
AmaraI can sell that protocol. What I can't sell is trusting a two week number to someone I'm coaching who limps into week nine because their twenty miler went sideways, happens every single cycle.
MilesThere's your favorite argument again!
AmaraBecause it's true-most of the damage happened weeks before anyone even thinks about lifting.
MilesSure, but that's a reason to fix the long run, not to just bail on lifting early out of habit.
AmaraFair enough.
MilesSo two sessions through peak, one in taper, done four or five days out.
AmaraAnd that frees up recovery capacity too; less time under the bar means more energy for everything else.
MilesOh, this is where it gets good, which opens up the fueling and sleep questions nobody actually plans for.
AmaraOh, the taper appetite thing is real; I texted an athlete about this last week, actually. They're eating like they're still running eighty miles a week when they've dropped to twenty; the math doesn't compute.
MilesAnd the anxiety that comes with feeling sluggish while doing less, that's coming up!
AmaraSo with that recovery capacity freed up, the real fight becomes what you're actually eating. Please no more carb load horror stories. My stomach still remembers 2019. I learned the hard way that loading doesn't mean doubling pasta at 10pm.
MilesThis one's subtler. Volume's dropping, but your glycogen stores still need topping off and appetite doesn't always cooperate.
AmaraBecause you're not burning 18 miles a week. weak anymore, so you're just not hungry. I've watched so many athletes convince themselves they're broken because their appetite suddenly makes biological sense.
MilesRight. The personal trainer taper guide from Shift to Strength flags exactly that. Glycogen loading has to stay intentional even as mileage drops.
AmaraAnd protein?
MilesStays high. You banked strength all summer lifting. Don't starve that muscle.
AmaraInteresting. What about hydration since you're not sweating? WEEDING THROUGH SIX MILE EFFORTS ANYMORE.
MilesElectrolyte needs actually drop with volume, but a lot of runners keep chugging sports drink out of habit and just get bloated.
AmaraHa ha ha! Guilty! By day seven I've turned into a walking Gatorade ad. Which, Plot twist, is exactly why I show up to the start line bloated the first two miles.
MilesOkay, your actual confession now.
AmaraI mean every single taper, day nine hits and I'm convinced my legs have filed for retirement and I'll text someone panicked and they're like, that's literally normal.
MilesHeavy legs in taper week are completely normal. Fluid and glycogen
Speaker 4stores are all full.
MilesCan glycogen shifts settle in? Your fitness didn't go anywhere.
AmaraTell that to my brain at 6 a.m.
MilesSleep is the real training session you've got left. Growth hormone, tissue repair, none of that stops just because miles did.
AmaraThat one I believe. I actually do sleep better during taper, probably because my nervous system finally stops screaming and my cortisol actually bottoms out for once.
MilesExactly the point.
AmaraThe mental side's brutal though. Three weeks of doing less while feeling worse, and that's when someone I'm coaching inevitably panics and adds stuff. And I mean stuff.
MilesAdd stuff.
AmaraRandom health sprints just to feel it 10 miler the week before? I've had to talk athletes off that ledge more times than I can count.
MilesWhat's the tell when someone's about to do it?
AmaraThey start saying they're just testing their legs. I've talked enough people down from that one to know testing three days out ends the same way, blunted race day.
MilesThat's a good one.
AmaraShort strides work better. Race-pace pickups. Four times a hundred meters, fast, done. Reminds your legs what fast feels like without wrecking them.
MilesAnd remind your brain you're not broken.
AmaraRight. Sharpness comes back in five minutes, not five miles.
MilesPlaying fully. Which is good because apparently some people handle taper restlessness. by signing up for a Hyrox mid block.
AmaraOh, no, no, no, no!
MilesBoxrox reported Hyrox as expanding to two million athletes across a hundred and seven race weekends for the twenty twenty-six twenty twenty-seven season.
AmaraSurprised, laughing) A hundred and seven? Okay, so there's definitely opportunity for bad decisions.
MilesOne hundred and seven. Plenty of dates; none of them belong three weeks before your marathon.
Speaker 3That Hyrox tease from earlier turns out the numbers are wild.
MilesRight. Boxrox broke it down this week: 107 race weekends, 6 continents.
Speaker 3Six continents! That's basically everywhere but Antarctica.
MilesGive it time. 2 million athletes expected for the 26-27 season.
Speaker 3Up from over a million and a half this past year.
MilesAnd Boxrox says some markets are stretching into ten day residencies now, instead of just a weekend.
Speaker 3Ten days; that's not a race, that's a festival.
MilesRox Lyfe reported new host cities too: San Diego, Portland, Bari, Nagoya. Nagoya?
AmaraNagoya is interesting; season runs through the spring, right?
MilesAthletech News says it ends at the Hong Kong World Championships in June twenty seventh.
AmaraOkay, but here's my worry: more races means more temptation to squeeze one in mid taper.
MilesDon't. Sequences—don't stack. There's a Hyrox weekend almost every month now, you don't need this one.
AmaraOkay, give me the three lines. What do people actually do this week?
MilesTwo lifts through peak week, same weight, less volume.
AmaraOne lifts during taper (light, just to keep the signal on). Gym's closed
Milesfour days out, no exceptions.
AmaraAnd after the race?
MilesRebuild strength from week one.
AmaraRight.
MilesDon't wait for it to come back by itself.
AmaraTwo lifts, one lift, four days dark, then rebuilt.
MilesThat's the whole plan.
AmaraGo run your race; we'll be here when the legs come back. Okay, so if there's one thing to carry out of today, strength training and tapering aren't enemies—lighten the volume, not the load.
MilesRight. And don't panic add a Hyrox week in mid taper just because BOXROX says the calendar's exploding. Save it for after.
AmaraGuilty of wanting to sign up on the spot.
MilesHeavy legs, bad sleep during taper week—normal, not a red flag.
AmaraExactly—trust the plan you built in week fourteen.
MilesAll right, that's it for us today.
AmaraGot a blind spot in your own training you want us to dig into?
MilesDrop it in the reviews or tag us at Full Spectrum Fit. We read everything.
AmaraNew episodes every Tuesday, so we'll see you right back here.
MilesRest up, taper smart, and we'll catch you next week.
AmaraBye, everyone.
