Why most pre-workouts fail endurance athletes
Most pre-workouts are built around one thing: a large dose of caffeine. It works until it doesn't. Caffeine spikes, crashes, disrupts sleep, builds tolerance fast, and creates a dependency loop where you need more to feel the same effect. That's not performance. That's borrowed energy you pay back later.
Endurance athletes have a different need. You're not looking for a 20-minute window of intensity before your body shuts down. You need sustained output across an hour or more with your head in the game the whole way through.*
Extra Mile uses six clinically-studied ingredients to deliver exactly that: increased blood flow, improved oxygen efficiency, sustained mental clarity, and cellular energy production without a single milligram of caffeine.*
Because Extra Mile is caffeine-free, it works with whatever caffeine routine you already have… morning coffee, race-day espresso, or none at all. Stack it freely without worrying about overdoing stimulants.*
Extra Mile vs. caffeinated pre-workouts
Extra Mile®
✓ Sustained energy, no spike
✓ Works with your caffeine routine
✓ Safe for evening training
✓ No tolerance buildup
✓ Targets blood flow + VO2
✓ No jitters or anxiety
Caffeinated Pre-Workout
✗ Spike then crash
✗ Stacks on top of daily caffeine
✗ Disrupts sleep if taken late
✗ Tolerance builds fast
✗ Masks fatigue, doesn't fix it
✗ Common source of jitters
The difference: Extra Mile addresses the actual physiology of endurance performance including blood flow, oxygen efficiency, cellular energy, and sustained focus without borrowing against tomorrow.*
6 key ingredients
Who it's for
You already know caffeine has limits. You've felt the spike, the crash, the 3pm wall, the poor sleep after an evening session. Extra Mile is the pre-workout for athletes who want something smarter.
Who need sustained output across an hour or more, not a 20-minute caffeine window
Who can't take a stimulant pre-workout without wrecking their sleep but still need real performance support
Who already get their caffeine from coffee and want a pre-workout that complements, not duplicates, it
Who need more and more to feel anything and want off that treadmill without losing their edge
Dynamine™ kicks in within 15 minutes. You'll notice the mental clarity before you even warm up.*
L-Citrulline and beetroot improve blood flow and oxygen delivery. Efforts that used to feel hard start feeling more manageable.*
Energy that builds and holds, not spikes and drops. You finish your session feeling strong instead of wiped out.*
No caffeine means no disrupted sleep. Train at 7pm and still fall asleep at 10pm.*
Most pre-workouts use caffeine as a shortcut. Extra Mile is caffeine-free by design because many athletes already have caffeine in their routine, because caffeine builds tolerance fast, and because it disrupts sleep when taken too late in the day. Instead, Extra Mile uses Dynamine™ and TeaCrine® for clean, sustained mental energy without the crash, plus L-Citrulline, beetroot, elevATP®, and Senactiv® to address the actual physiology of endurance performance.*
Dynamine™ (Methylliberine) is a fast-acting alkaloid that activates dopamine receptors and blocks adenosine, the compound responsible for fatigue signals. It delivers rapid mental clarity and energy onset within 15 minutes. TeaCrine® (Theacrine) is structurally similar to caffeine but with a longer half-life and no tolerance buildup. It extends the energy window that Dynamine™ opens. Together they provide sustained focus throughout your session.*
Yes. This is exactly why we made it caffeine-free. Extra Mile is designed to work with your existing caffeine habits, not against them. Take your morning coffee as usual, then mix up Extra Mile 20–30 minutes before your session. No risk of overcaffeinating, no jitters from stacking stimulants.*
Yes. Because Extra Mile contains zero caffeine, it won't interfere with sleep regardless of when you take it. This makes it one of the only pre-workouts suitable for athletes who train after work or in the evening.*
elevATP® is a patented ingredient combining ancient peat extract and apple polyphenols. It has been clinically studied for its ability to increase endogenous ATP production, adenosine triphosphate, the primary energy currency your cells use during exercise. Studies show it supports peak power output and explosive performance during high-intensity efforts.*
Yes. The full RNWY stack is designed to be a system. Take Foundation in the morning, Extra Mile 20–30 minutes before training, Salty Carbs during sessions lasting 60+ minutes, and Complete Protein post-workout. There are no conflicts across any combination.*
Clinically-studied endurance performance. Zero caffeine.
Six clinically-studied ingredients. Sustained energy. Increased blood flow. Sharp focus from start to finish without a single milligram of caffeine.*

"I’ve never really taken pre-workout before because most of them give me jitters or a weird crash, so I usually avoid them. This one feels totally different. The energy feels really smooth and focused, not overwhelming at all. It’s been especially nice on harder workouts when I want a little extra boost without feeling wired."
"I take the Extra Miles before I go on a run and can definetly feel the difference in energy. It keeps me going and helps me accomplish my daily running goals!"
"Love the extra mile! You can really feel it kick in when doing speed or threshold workouts. I use it before all of my races!"
"finally a pre workout that doesnt make my heart race or face itch. thank you RNWY"
"Not a fan of the aftertaste. I rewlly wanted to love it."
"I used it and threw up three times on my run. The watermelon is overwhelming and the overall experience of it was sick-making. To give it a fair chance, I tried it a second day and same fail. It's too much. Do not recommend."
"Absolutely love this product. It helps me focus on my runs and gives me an extra boost since I mostly stick to no caffeine before runs because of GI issues. Love the sour watermelon flavor."
"GREAT PRODUCT, BETTER RESULTS. Definitely an edge and the name speaks for itself!"
"This product does work for me. I would recommend trying it if you need a boast before a workout or long run."
"Love this stuff! It’s gentle on the stomach and the only pre-workout I can take. It’s a subtle pre-workout that gets you ready to work out but doesn’t make you shaky."
