Can Jacob Kiplimo fix the pacing collapse that wrecked his 2025 Chicago Marathon title defense, or does an even deeper 2026 field just give him more runners to fade in front of on October 11? This Tuesday's episode breaks down what actually happened at his 35km split, why his negative-split London race offers a genuinely hopeful sign, and how Chicago's stacked field, including Lokedi, Kosgei, Kipruto, Hicks, and defending champion Hawi Feysa, raises the stakes for his rematch. Listeners will learn how the 2025 fade unfolded mile by mile, what London's splits reveal about Kiplimo's current fitness, and why depth of competition changes the calculus for pacing strategy. The hosts land on hedged predictions and tie the story back to a core theme: raw fitness means little without disciplined execution.

What happens when a marathoner runs through 35 kilometers on pace to break the world record and still doesn't run his personal best? This episode breaks down Jacob Kiplimo's 2:02:23 finish at the Chicago Marathon, splitting the race down to the mile to show exactly where the pace fell apart.

Listeners will learn how glycogen depletion and pacing psychology combine to produce a fade with no floor, why Chicago's flat 187-foot elevation profile rules out terrain as an excuse, and what Kiplimo's subsequent 57:20 half marathon world record reveals about judgment versus fitness. The conversation turns the lesson toward anyone who's ever gone out too fast in a race of their own, tying elite marathon strategy to everyday training decisions.

• How a 13:58 opening 5K set up a collapse that started at 35K and never leveled off
• Why experts frame the fade as a physics problem rather than a willpower failure
• What Kiplimo's return to defend his title on October 11, 2026 says about learning from a bad pacing call

This is full-spectrum fitness thinking: using elite race data to sharpen the decisions recreational runners make every time they step to a start line. New episodes drop every Tuesday.

Can going to bed earlier do more for taper-week performance than half the gadgets athletes buy? Amara and Miles dig into the sleep extension research, starting with a headline stat on athletes who were already sleeping well and still saw gains in neuromuscular output and pain tolerance. They trace how researchers engineered extra sleep in crossover and rugby-team trials, then dissect a flagship hockey study that showed real cognitive and fatigue benefits alongside honest null results. Listeners learn how much extra sleep actually matters (often less than two hours), why pain tolerance and mood show the clearest wins, and how to build a realistic bedtime shift for taper week without banking one good night. It's a fitting full-spectrum turn: real recovery starts before the workout ever happens.

What actually happens when the fastest marathoner alive gets sidelined by a stress fracture weeks before his comeback race? Miles and Amara dig into the conflicting reports around Sabastian Sawe's withdrawal from Berlin and use it to explain the bone-stress mechanism behind tibial fractures at every level of running, from elite to recreational.

Listeners will learn how mileage ramps outpace bone remodeling and where that risk actually comes from, how to read early warning signs before a stress reaction becomes a full fracture, and what concrete audit steps to run on their own training log this week. The hosts also work through why fracture location matters more than severity labels, and where they land on ramping mileage conservatively versus reading individual tolerance. It's a reminder that bone health is the training dimension recreational runners skip most, and full-spectrum fitness means auditing that blind spot before it becomes an injury.

How do you build a sane training year when the Hyrox calendar now stretches across 107 race weekends on six continents? Miles and Amara break down what the expanded season and new rulebook mean for anyone who wants to race often without wrecking their body or their schedule.

Listeners learn how the global race footprint and denser North American schedule change the cost–benefit math of frequent racing, how the updated rules raise the stakes for under-recovered starts, and how to map race choices onto a realistic year-long plan instead of treating every weekend as a peak attempt. You also hear practical guidance on balancing performance goals, travel, and recovery so Hyrox complements your life rather than consuming it. New every Tuesday, Full Spectrum Fit uses races like Hyrox to show what full-spectrum planning looks like across an entire training year.

Why did Miles's stomach fall apart at mile fourteen of an eighteen-mile long run, despite doing everything right the night before with the classic pasta dinner? Amara breaks down why pre-race carb loading fails most recreational runners and what actually works with Berlin five and a half weeks out.

Listeners learn the real gram-per-kilo carb targets for race week and why under-eating, not overeating, is the common mistake. The episode covers how SGLT1 and GLUT5 sugar transporters raise the ceiling on carbs absorbed per hour, how to read that science on a gel label, and a two-week gut-training protocol to start now instead of during taper. Full-spectrum fitness means training the gut with the same intention as the legs and lungs.

What actually happens inside an Achilles tendon that hurts on the first steps of a run but eases once you're warmed up? Miles and Amara open up about their own flare-ups this week and use them to dig into the science of tendinopathy just as most fall marathoners hit peak mileage for Berlin, Chicago, and New York.

Listeners will learn why tendon pain is a load-tolerance problem rather than inflammation, why aggressive calf stretching can make insertional Achilles pain worse, and how to use a 24-hour pain rule to decide whether to run, rest, or scale back a race plan. Amara also breaks down a new loading trial and lays out an honest six-week triage plan for anyone racing on a flaring tendon. It's a full-spectrum look at balancing ambition with the biology that actually limits it, out this Tuesday.

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.

What actually separates natural muscle building from enhancement, and does the math behind those viral "is he natty" videos hold up? Miles and Amara dig into the FFMI formula fueling the Jeff Nippard debate, tracing its 25 cutoff back to a 1995 study of 157 lifters. Listeners learn how that number was calculated, why body fat measurement error and DEXA scan margins can shift someone across the natural line entirely, and what Nippard has said publicly about inheriting physique traits from his bodybuilder parents.

The conversation moves past internet judgment toward a more useful question: understanding your own genetic ceiling instead of measuring yourself against outliers. That's the full-spectrum lens this show keeps coming back to. New episodes drop every Tuesday.

Marathon training season is here, and the question every lifter signing up for a fall race eventually asks is the same: how much squat strength will this cost me? Miles and Amara break down what really happens to strength during high-mileage endurance training, separating outdated interference-effect fears from what current research and their own training logs actually show.

Listeners will learn why volume matters more than workout order when combining lifting and running, how to structure a training week that includes squats, hard runs, and a long run without one wrecking the other, and why underfueling during marathon builds threatens muscle more than the squat rack does. The episode closes with recovery demands that expand with mileage and one concrete decision to make this week.

It's a practical look at balancing strength and endurance without picking sides, which is the whole point of training full spectrum.
