How to pick a correct Marathon pace?

we see the results but more important to understand the results from science and see how we can all look to marathon in different way

Andreas Almgren for the Win and History​1. Unmatched Speed Reserve and High-End Aerobic Capacity​Almgren carries a speed profile unlike nearly any debutant in modern Major history:​The 1:45 to 58:06 Range: From an 800m World U20 bronze medalist (1:45.59) and sub-12:45 5,000m runner to running 58:06 to win the World Road Running Half Marathon title in Copenhagen, his velocity at VO2 max and lactate threshold is world-class.​Effortless Half Pace: Running 2:06–2:08 pace in New York requires averaging ~4:48–4:53 per mile. To a runner who covered 13.1 miles at 4:26/mile pace (2:45/km) in Copenhagen, 4:50 pace sits exceptionally deep in his aerobic comfort zone.

​Training above 2,000 meters isn’t just about mental grit—it is a physiological reset that permanently shifts your aerobic ceiling.​When oxygen partial pressure drops, your body triggers an acute survival response led by the kidneys, boosting natural Erythropoietin (EPO) production to synthesize more red blood cells. The payoff isn't just surviving thin air; it’s what happens when you return to sea level with an expanded delivery system.Train smart at altitude: keep easy days strictly governed by heart rate rather than ego, hydrate aggressively against thin air loss, and let the adaptations do the work when you race flat.

Can logging miles on a belt actually translate to performance on the road and track, or are you just spinning your wheels?​In this episode, we break down the real biomechanical and physiological utility of treadmill training. Moving past the myth of the "dreadmill," we dive into how the forgiving deck surface provides critical impact moderation to spare joints and connective tissue during high-volume blocks. We also analyze how the uniform moving belt naturally promotes a tighter, quicker cadence by reducing overstriding, and why the micro-managed environment of the treadmill—from precision pacing to controlled incline—makes it one of the most effective tools for locking in specific stimulus without external variables.​In this episode, we cover:​Impact Reduction & Soft Ground Dynamics: How the reduced peak ground reaction forces can keep your weekly mileage high while keeping legs fresh.​Cadence & Neuromuscular Tuning: Why the fixed belt speed forces a faster turnover, reduces braking forces, and dials in running economy.​Dialed-in Control: Leveraging zero-variable pacing, grade control, and micro-climates for targeted threshold and recovery work.​Road Translation: How to structure your indoor sessions so the fitness converts seamlessly to the asphalt.

The Problem: The entire running internet treats Zone 2 as the baseline for "easy recovery." In reality, Zone 2 is aerobic development work, not pure physiological flushing.​The Hook: If your heart rate instantly shoots to 135–145 bpm the moment both feet leave the ground, you do not have an "easy" running gear. Your aerobic floor is too high.​The Analogy: Compare it to a manual transmission car. Elites have a true 1st gear (Zone 1) for pure cruising and recovery. Most amateurs only have 2nd, 3rd, and 4th gears—so their "idling" is already burning significant metabolic fuel.

​On one side, aiming for a "delusional" breakthrough can spark crazy motivation, shift your mindset, and expand what you think is possible. But chase it blindly without respecting your current physiology, and it can leave you crashing into reality. On the other hand, setting strictly "realistic" goals protects your consistency and keeps training safe—yet play it too safe, and you end up leaving your best potential locked away on the course.​So, which mindset actually drives long-term breakthroughs? We dive into:​Why swinging too far toward fantasy leads to chronic overreaching and mental fatigue.​The trap of playing it safe with conservative, predictable targets.​How the most successful athletes navigate the tension between ambition and data.​A clear, practical framework to calibrate your next marathon, half-marathon, or 5K goal so it challenges your ceiling while keeping the daily work sustainable.​Whether you're gearing up for your next training block or questioning if your current target pace is out of reach, this conversation will help you find the clarity you need on the starting line.

If you want to run a breakthrough marathon, stop obsessing only over your 20-mile long runs and take a hard look at your 5K personal best.​In this episode of Run Planet 365, we break down Speed Reserve—the single most overlooked physiological metric that determines whether your goal marathon pace feels like a controlled cruise or a suffocating redline.​Most marathoners hit a plateau because they rely on one tool: adding more slow miles. Over time, they become one-speed "diesel engines" who can run all day, but lack the top-end mechanical gear required to make marathon pace feel effortless. We dissect the exact mathematical relationship between your short-distance speed and your 26.2 ceiling, explaining why raising your maximum velocity (the 86–88% rule) is the key to running faster without blowing up at mile 20.​Whether you are targeting a sub-2:30 elite qualifier, hunting a sub-3:00 milestone, or chasing a personal best in your 40s, this episode delivers a blueprint to expand your engine.
