The Formula

Before. During. After.

Every serious endurance athlete needs three things: fuel to start, fuel to sustain, and fuel to rebuild. This stack covers all three with research-backed products.

01

Prime The Engine

Ignite delivers clean energy and mental focus before your session. Beta-alanine buffers lactic acid buildup, L-citrulline improves blood flow and oxygen delivery, and caffeine sharpens focus for long efforts.

Beta-Alanine 3.2g
02

Fuel The Distance

Motion keeps you going when glycogen runs low. Cluster dextrin delivers steady carbs with zero GI distress, BCAAs prevent muscle breakdown, and electrolytes replace what you lose through sweat. The gold standard for intra-workout fueling.

Carbs Per Serving 30g
03

Rebuild Stronger

Grow provides 25g of fast-absorbing whey isolate post-session. Endurance training breaks down muscle — your next workout depends on how well you rebuild. Protein is non-negotiable for serious endurance athletes.

Protein Per Serving 25g
Daily Protocol

Your Training Day

Four touchpoints across your training day. Simple timing, research-backed doses, real-world tested by thousands of endurance athletes.

Pre-Session

Ignite

1 scoop, 20 min before

Full scoop with 8-12oz water before your run, ride, or session. Kicks in right as you start, sustains through the first hour.

During Workout

Motion

1 scoop per 60-90 min

Mix with water in your bottle or hydration pack. Sip steadily throughout your session — no stomach upset, no crashes.

Post-Session

Grow

1 scoop, within 60 min

25g whey isolate in water or milk after training. Fast absorption kicks off the repair process before you even hit the shower.

Throughout Day

Grow

Second shake optional

A second shake helps endurance athletes hit daily protein targets (0.6-0.9g per lb) — often underestimated in distance sports.

What Customers Say

Real Results, Real Athletes

Runners, cyclists, and triathletes use the Endurance Stack to push further, finish stronger, and recover faster. Here's what they're saying.

★★★★★

Motion is a game changer for long rides. I've tried every sports drink on the market and most of them wreck my stomach at hour three. This stuff goes down clean and keeps my watts up the whole ride. Finally something that actually works for 4+ hour sessions.

★★★★★

Training for my first ultra and the stack has been a lifesaver. Ignite gets me out the door at 5am, Motion keeps me fueled through long runs, Grow helps me recover for back-to-back training days. Dialed in.

★★★★★

Cluster dextrin is the real deal. I used to bonk hard around mile 18 of my long runs no matter how much gel I took. Switched to Motion and the wall just doesn't hit anymore. Best investment I've made in my training.

The Carbohydrate Problem

Your body stores roughly 1,800-2,200 calories of glycogen — your primary fuel for any session over 60 minutes. Run or ride hard enough and you'll burn through that reserve in 90-120 minutes. That's when the wall hits: legs go dead, pace drops, and brain fog sets in. This isn't weakness — it's physics.

The only way around it is to deliver carbohydrates during the session. Research shows trained endurance athletes can absorb 60-90 grams of carbs per hour when the fuel source is right. The problem: most traditional carb sources (maltodextrin, glucose, fructose) cause stomach distress well before you hit those intake levels.

Key Takeaway Your body can only use what it can absorb. Choosing a premium carb source isn't optional — it's the difference between finishing strong and hitting the wall.

Why Cluster Dextrin Is The Gold Standard

Cluster dextrin (also called highly branched cyclic dextrin, or HBCD) has a high molecular weight and unusually low osmolality. Without the jargon: it empties from your stomach faster than any other carbohydrate source, causes virtually zero GI distress, and delivers steady energy without the blood sugar crashes of simple sugars.

A 2006 study published in the Journal of the International Society of Sports Nutrition compared cluster dextrin to glucose and maltodextrin during endurance exercise. Cluster dextrin significantly increased time to exhaustion and rated as easier on the stomach in subjective measures. It's the carbohydrate source used by professional cyclists and ultra runners for a reason.

BCAAs And Muscle Breakdown

Long endurance sessions break down muscle tissue for energy — especially as glycogen runs low. This is called muscle protein breakdown, and it's why ultra runners finish races visibly smaller and why cyclists lose leg strength over a big training block. BCAAs (leucine, isoleucine, valine) delivered during exercise help preserve lean muscle by providing alternative fuel substrates.

Motion includes BCAAs alongside the cluster dextrin, which is why it works better than a pure carb drink for long sessions. You're fueling the work and protecting the engine at the same time.

Protein Needs For Endurance Athletes

Most endurance athletes under-eat protein. The outdated RDA (0.36g per lb) was calibrated for sedentary adults — it's nowhere near enough for someone running 40 miles a week. Current research suggests endurance athletes need 0.6-0.9g of protein per lb of bodyweight for optimal recovery, immune function, and adaptation.

For a 160-pound runner, that's 96-144g of protein per day — a lot more than most endurance athletes consume. Two scoops of Grow cover 50g of that target with high-leucine whey isolate, making it easier to hit the number without forcing another chicken breast at every meal.

The Caffeine Edge

Caffeine is one of the few legal ergogenic aids with strong scientific support for endurance performance. Multiple meta-analyses show caffeine intake of 3-6mg per kg of bodyweight improves endurance performance by 2-4% — which in a marathon is the difference between a PR and a slow day. Ignite delivers an effective dose in a clean, jitter-free formulation.

The Endurance Stack is built for runners, cyclists, triathletes, rowers, and any athlete training for sustained sessions of 60 minutes or longer. If your sessions are under 45 minutes, you likely don't need the intra-workout carbs from Motion — the Muscle Growth Stack may be a better fit for you.
Cluster dextrin (also called highly branched cyclic dextrin, or HBCD) is a premium carbohydrate with a high molecular weight and low osmolality. In practical terms, it empties from your stomach faster than traditional carbs, causes no GI distress during exercise, and delivers steady energy without sugar spikes or crashes. It's the gold standard for intra-workout fueling in endurance sports.
Motion contains electrolytes to replace what you lose through sweat during training. For sessions under 90 minutes in moderate conditions, Motion alone is typically enough. For longer sessions, hot weather, or heavy sweaters, you may want to add a dedicated electrolyte supplement. Listen to your body and adjust based on how much you're sweating.
Yes, significantly. Standard sports drinks use high-fructose corn syrup or maltodextrin, which cause stomach upset at higher intake rates and spike blood sugar. Motion uses cluster dextrin, which allows for higher carb delivery (60-90g per hour) without GI problems — critical for endurance performance. It also includes BCAAs to help preserve muscle during long sessions.
Endurance training breaks down muscle tissue just like strength training does — sometimes more, due to the sheer volume of sessions. Protein intake of 0.6-0.9g per pound of bodyweight helps repair muscle, support immune function, and prevent overtraining. Many endurance athletes under-eat protein and pay for it with slow recovery, frequent injuries, and stalled progress.
One container of Ignite provides 30 servings, Motion provides 30 servings, and Grow provides 30 servings. At standard use this gives you a full 30-day supply. Heavy training weeks with 5-6 long sessions will use Motion faster — plan accordingly or order a second container.
