Four formulas. One system. The stack for the back half — and the next morning.

$129.00

Oxygen and muscle performance that holds through the run, not just the first mile.
Recovery that actually happens — cardiovascular, muscular, and neural.
Sleep deep enough that tomorrow's training doesn't start from a deficit.

Creatine support for muscle performance and sustained effort.
Better oxygen delivery where pace is won or lost.
Cardiovascular function that supports your entire aerobic system.
Sleep deep enough that recovery is actually recovery, not just time lying down.
Legs that feel fresher on back-to-back training days.
A system built for 3–4 weeks of consistent use alongside training — not a single-run miracle.
Made for the routine, not the exception.

Formula 1: Creatine Monohydrate (5g per serving)

Ingredients: Creatine Monohydrate
What it does: Supports ATP recycling in muscle, which means your muscles have more energy available to hold effort. Research shows it takes 3–5g daily for weeks to matter — which is why a single dose of anything won't work.
Why this matters for runners: You don't need bodybuilder-level muscle. You need the energy systems in your legs to stay available longer. Creatine does that.
Dosing: 1 scoop in 8oz water, 1–2x daily

Formula 2: Beetroot Powder (one scoop, ~97.5g per serving)

Ingredients: Beet Root Powder (Beta vulgaris) (root), Hibiscus Powder (flower), Apple Juice Powder (fruit), Stevia Extract (leaf), Maltodextrin
What it does: Beetroot contains nitrates, which your body converts to nitric oxide — a vasodilator. Better blood vessels = better blood flow = more oxygen to your legs.
Why this matters: Oxygen availability is what caps your pace before your will does. This directly addresses that.
Dosing: 1 scoop in 6–8oz cold water, once daily, consume within 10 minutes

Formula 3: Omega-3 (EPA 180mg + DHA 120mg per serving)

Ingredients: Fish oil concentrate, EPA, DHA, softgel (gelatin, glycerin, water), Vitamin E
What it does: EPA supports normal cholesterol and triglyceride levels; DHA supports brain function and vision. Together they support cardiovascular function.
Why this matters: Your heart is the engine. Omega-3s keep that engine running smoothly — which means sustained output without the system taxing itself.
Dosing: 1–2 softgels daily with meals

Formula 4: Sleep Support (2 capsules once daily, 20–30min before bed)

Ingredients: Magnesium citrate, Vitamin B6, Calcium carbonate, Melatonin, Sleep Formula Proprietary Blend (L-Tryptophan, Lycium, Chamomile, Lemon Balm, Passion Flower, L-Taurine, Hops, St. John's Wort, GABA, Chinese Skullcap, L-Theanine, Ashwagandha, Inositol, 5-HTP)
What it does: Supports normal sleep cycle (melatonin) + nervous system function (magnesium, B6) + relaxation (botanicals + GABA). Together, they support the depth of sleep where muscular and neural recovery happens.
Why this matters: Most runners go hard in training and then sleep like garbage. Adaptation doesn't happen in the training; it happens in recovery. This makes recovery actually happen.
Dosing: 2 capsules, 20–30 minutes before bed

You can't train yourself past a broken recovery cycle.

Most beginner runners think pace comes from effort alone. It doesn't. Pace is decided by three systems running in parallel: muscle energy availability (creatine), oxygen delivery (beetroot), cardiovascular efficiency (omega-3), and the sleep depth where adaptation happens (sleep support).

If any one of those is weak, your pace falls. Most runners blame willpower. It's usually one of those four systems.

The Running Stack fills all four — as a system, at consistent doses, over the weeks it takes to matter. You can't out-train bad recovery. This is the recovery cycle that makes training actually compound.

Frequently asked questions

No. Creatine supports ATP recycling in muscle cells — energy availability. Runners need that as much as anyone else. The difference is you're not using it for bulk; you're using it to hold pace longer. And at 5g daily, it's the dose shown in research to matter. Your gym won't give you that from diet.

It draws water into muscle cells — which means your muscles have more water, not less. The trade-off is you have to drink more water overall. That's it. Most beginners skip it because they heard "dehydration" and didn't dig deeper.

Did you take the dose that matters? This is 97.5g per serving — the amount shown in research to support nitric oxide production. A bite of a beet doesn't count. You need consistent dosing, and you'll feel it in breathing ease and pace sustainability.

They do. But they're working at the cardiovascular level — which is where endurance actually lives. You won't feel it like you feel creatine or beetroot, but your heart will be more efficient, which means your output is more sustainable. That matters over weeks, not days.

Most runners think "sleep" means "unconscious for 8 hours." It doesn't. Deep sleep is where muscular and neural recovery happens. If you're training hard but sleeping shallow, you're missing the adaptation. The formula supports sleep depth — which is what actually matters for recovery.

You could. But you'd be addressing one system, not the whole cycle. Creatine supports muscle energy. Beetroot supports oxygen delivery. Omega-3 supports cardiovascular function. Sleep supports adaptation. Together they're a cycle. Apart, each one is incomplete.

Creatine: 2–3 weeks in, your legs will have more energy available at pace.
Beetroot: First 5–7 days, easier breathing and less ragged feeling at effort.
Omega-3: Subtle, works over weeks at the cardiovascular level.
Sleep: First night you'll notice deeper sleep; recovery amplifies over weeks.

It's the opposite. Elite runners already have training volume and base building experience. Beginners are the ones hitting pace walls, struggling with recovery, and wondering why sleep isn't enough. That's exactly what this addresses.

Completely. Aerobic engine is aerobic engine. Whether you're running or cycling, you need muscle energy (creatine), oxygen delivery (beetroot), cardiovascular function (omega-3), and recovery (sleep). The physics don't change.
