Hydration Sachet Stack - Variety Pack
Cramping. Pace Fade. Inconsistent Energy. It's Not Your Fitness. It's How You Hydrate.
Your calves pump 70% of your blood back from your legs. Scientists call them "the second heart." When hydration fails, so does the system. 11 reasons why — and how to fix it.
READ THE 11 reasons why ↓
Most runners only think about hydration during the run. By then, they're already compromised. Here's why fixing it unlocks the consistency you've been chasing.
.01
Dehydration doesn’t just make you thirsty. It makes your heart work 15–20% harder.
Blood composition changes based on hydration. Properly hydrated blood flows smoothly. Under-hydrated blood thickens, and viscosity increases.
Your heart compensates:
more beats per minute, stronger contractions,
more beats per
increased effort to maintain the same output.
minute, stronger contractions, increased effort to maintain the same output.
Strategic hydration maintains optimal blood viscosity. Your heart supports performance instead of fighting resistance.
Eliminate The Cardiovascular Tax
.02
Your second heart pumps 10,000 times per run. Here's why every stroke matters.
Every footstrike activates your calf pump, moving up to 70% of venous blood from your legs back to your heart.
Scientists call it "the second heart." Not a metaphor. A real pump.
When blood volume drops and viscosity increases, your calf pump faces mechanical resistance, thicker blood that's harder to move. Your calves work overtime, burning extra energy.
Strategic hydration maintains optimal blood viscosity. Your calf pump moves blood efficiently instead of fighting resistance.
Support Your Calf Pump
.03
Less blood volume means less oxygen delivered. It’s that simple.
Think of your blood like delivery trucks carrying oxygen to your muscles. Properly hydrated, every heartbeat sends a fuller truck. More oxygen is delivered.
When blood volume drops, each heartbeat sends a smaller truck. Less oxygen reaches your legs with every pump.
Your muscles need oxygen. They're not getting enough. So they switch to anaerobic metabolism, creating lactic acid fast. Your legs burn earlier than expected, miles before they should.
Optimize the delivery. Everything changes.
Optimize Your Oxygen Delivery
.04
Pace fade isn’t part of running. It’s a symptom of unsupported circulation.
Most runners accept pace fade as normal: "Miles 1-5 always feel better than miles 6-10."
It doesn't have to be.
Pace fade happens when your circulatory system can't maintain output. The cascade:
Blood volume drops
Heart rate climbs
Oxygen delivery decreases
Lactic acid spikes
Pace fades
This isn't inevitable. It's preventable.
When circulation is properly supported, the cascade doesn't start. Blood stays fluid. Heart rate stays controlled. Mile 10 feels like Mile 3.
Eliminate Pace Fade
.05
Cramping isn’t random.
It’s your muscles signaling that circulation failed.
Mile 6. You're on pace. Then your calf locks up. Run over.
You think: "Pushed too hard. Should have stretched more. Bad luck."
None of that's true.
Cramps happen when muscles can't get what they need through circulation.
Blood volume drops
Circulation slows
Electrolyte balance shifts
Waste accumulate
Muscles can't relax
Cramp
It's not bad luck. It's a mechanical failure.
Support circulation. Maintain electrolyte balance. Cramps stop.
Eliminate Cramping
.06
One bad recovery bleeds into the next session. Then the next. Then the next.
Here's how training falls apart:
Tuesday: Good session. Poor overnight recovery.
Wednesday: Start tired. Session quality drops.
Thursday: Start even more tired. Barely get through it.
Friday: You're cooked. Training is now damage, not adaptation.
It's not one bad session. It's compounding degradation.
Now flip it: Proper overnight recovery. You wake up ready every day. Each session builds on the last. By Friday, you're hitting PRs, not survival mode.
Engineer Compound Recovery
.07
That voice saying “slow down” isn’t weakness. It’s your brain running low on oxygen.
Mile 1: Mind sharp. Focused. Motivated.
Mile 6: Mind negotiating. "Maybe just slow down a bit..."
Mile 9: Mind screaming. "Why are we doing this? Just stop."
You think it's mental toughness failing. It's not.
Your brain runs on oxygen. When circulation is compromised and oxygen delivery drops, your brain gets less fuel. Mental performance degrades just like physical performance. That inner voice shifts from encouraging to begging you to quit.
It's not a weakness. It's biology.
Sharpen Your Mental Edge
.08
Training consistency becomes your superpower.
When hydration is consistent, training becomes predictable. Good days become normal. Progress becomes linear instead of chaotic.
Elite runners eliminated hydration as a limiting factor. Circulation stays stable. Performance stays repeatable. Training actually builds.
Build Consistent Performance
.09
Elite runners don’t chase “good days.” They make every day a good day.
You know what a good day feels like:
Legs feel light.
Pace feels easy.
Everything clicks.
Problem: Good days feel rare. Random.
Elite runners flipped this. Good days aren't rare. They're the standard. Because they eliminated what creates bad days.
Bad days happen when blood volume is low, circulation is compromised, and oxygen delivery drops.
Good days happen when those systems are supported.
Make Good Days Normal

Elite runners don’t just hydrate.
They hydrate strategically across three critical windows.
Most runners hydrate randomly: Drink when thirsty. Maybe during runs. Hope it's enough. It's not. And it's why performance stays chaotic. It's not. And it's why performance stays chaotic.
Elite runners support circulation across the complete 24-hour cycle:
Stage 1: Morning (Restore)
8 hours without fluid means blood volume is down. Morning hydration restores baseline before training starts.
Stage 2: Training (Maintain)
Sweat and effort deplete blood volume under load. Strategic hydration maintains circulation when stress is highest.
Stage 3: Overnight (Reset)
Most repair happens during sleep. Overnight hydration supports your second heart while you recover.
Three stages. Complete coverage. You start every run from optimal circulation, not deficit. Training works better. Recovery completes fully. Performance becomes consistent.
Support All Three Stages

Every runner has a breakthrough moment. This is yours.
You've been training hard for months. Maybe years. Putting in the work. Following the plan. Doing everything right.
But progress has stalled. Times have plateaued. The next level feels unreachable.
Here's your breakthrough: It's not your training. It's not your talent. It's not your effort.
It may be circulation.
Thicker blood, struggling calf pump, reduced oxygen delivery, pace fade, cramping, slower recovery, mental fog, they're all circulation problems.
And they're all addressable.
Support your second heart strategically.
Maintain blood volume.
Keep circulation efficient.
Workouts that felt impossible become doable. Paces that seemed out of reach become training zones. Race times that felt like distant goals become realistic targets.
You understand the problem. Here’s the solution.
For 11 reasons, we've shown you why circulation determines performance. Now here's how to optimize it.
Three formulas. Three critical windows. One complete system that supports your second heart exactly when it needs it.
STAGE 1: CORE HYDRATION / MORNING FOUNDATION
Restores blood volume after 8 hours without fluid. Prepares your second heart for the day ahead.

STAGE 2: ENERGY HYDRATION / TRAINING SUPPORT
Maintains circulation under load. Keeps your second heart pumping efficiently when stress is highest.
They work perfectly! I always struggle to find a pre-workout style drink that works for me; they're too caffeinated or loaded with filler ingredients, but this isn't! It kept me hydrated and caffeinated to get through both my interval run and weight lifting sessions.

STAGE 3: SLEEP HYDRATION / OVERNIGHT RESET
Supports circulation while you sleep. Enables the repair, recovery, and adaptation that happens overnight
LOVE the sleep hydration sachet. All of their hydration products have been absolute game changers for my marathon training. Having a specific product for each part of your training including your recovery is something I find so useful because now I know that hydration is something that isn't a factor that's slowing down my progress.

Real results. Real testimonials. Real customers.
Love this mix of sachets. I use the watermelon every morning, and now I have started drinking the sleep one an hour before bed, and it really helps with a really good restful night. Yet to try the race one but going for a run now so let's give it a whirl!

LOVE the rest and recovery! Ive been trying alot of different ones and so far cadence has worked the best! Im training for Boston and trying to find something to covers all aspects of my training and Cadence does! LOVE the Recovery! Great, non overpowering flavor like other tart cherry aids and has had the best effect on my Garmin sleep performance so far! I drink the Core every morning before I wven touch my coffee. Will continue to buy!
