Product Description
Most pre-workouts are built for weightlifters — high-stimulant, short-duration, crash-and-burn. When you're heading out for a 4-hour ride or a marathon-pace long run, that formula gets you 20 minutes of hype and then leaves you hollow. Here's what most athletes don't realize: the energy demand of endurance sport isn't just about caffeine — it's about blood flow, sustained output, and keeping your head in the game for hours.
PreRace by First Endurance is the only pre-workout designed specifically for the physiology of endurance athletes — cyclists, runners, and triathletes who need to perform at threshold for hours, not minutes.
Vasodilation That Actually Moves the Needle PreRace contains 1,500mg of Nitrosigine® — a patented form of arginine that opens up your blood vessels, getting more oxygen and fuel to working muscles. This isn't just "pump" marketing. In independent testing, Nitrosigine® measurably increases nitric oxide levels, meaning your cardiovascular system is running more efficiently from the first pedal stroke.
Energy Without the Crash Two hundred milligrams of caffeine pairs with 150mg of TeaCrine® — a compound structurally similar to caffeine but with a longer, smoother curve. Together they sustain mental sharpness and motivation for 2–3 hours without the spike-and-crash pattern you get from a double espresso or a conventional pre-workout. Two thousand milligrams of taurine helps buffer fatigue so your muscles keep firing when effort climbs.
Built-In Recovery Starter Five hundred milligrams of VitaCherry® Sport tart cherry extract — rich in the anti-inflammatory compounds that give cherries their deep red color — begins the recovery process before you're even done working. That's a level of forward thinking you don't usually see in a pre-workout.
Blend one scoop into 8–12 oz of water 30 minutes before your hardest efforts. At an independent SDSU cycling study, athletes using PreRace finished a time trial 3 minutes and 17 seconds faster and generated 15 additional watts of average power versus placebo. That's a measurable edge, not a feeling.
Mix PreRace with a scoop of EFS or EFS Pro to cover your carbohydrate and electrolyte needs for the session — that's exactly how First Endurance designed the system to work.
This isn't just another pre-workout. This is purpose-built race-day fuel for the athlete who needs to go long and go fast.

First Endurance PreRace Drink Mix FAQ's
Everything you need to know about First Endurance PreRace Drink Mix.
PreRace is a caffeinated pre-workout drink mix built specifically for endurance athletes — cyclists, runners, and triathletes. One scoop (5.8g) delivers 200mg caffeine, 2,000mg taurine, 1,500mg Nitrosigine® arginine, 500mg VitaCherry® Sport tart cherry extract, 500mg cacao extract, and 150mg TeaCrine® — all working together to increase energy, blood flow, and focus for long training sessions and races.
Mix one scoop with 8–12 oz of water about 30 minutes before your workout or race. Most athletes notice peak effect 30–45 minutes after drinking it, with the energy curve lasting 2–3 hours — timed well for a long ride warmup or a race start.
Each scoop has 200mg of caffeine — roughly two cups of coffee. It also includes 150mg of TeaCrine® (theacrine), a compound that extends and smooths the caffeine effect, so you get sustained alertness without the hard crash you'd get from the same caffeine dose alone.
Nitrosigine® is a patented, research-backed form of arginine that boosts nitric oxide production — the signaling molecule that tells your blood vessels to relax and open up. More open vessels means more oxygen and glucose delivered to your working muscles. For endurance athletes pushing at threshold for hours, that improved delivery is meaningful.
Yes — this is exactly how First Endurance intends it to be used. Mix one scoop of PreRace into a serving of EFS or EFS Pro before your workout. PreRace handles the stimulant, blood flow, and focus side; EFS covers your carbohydrates and electrolytes. Together they form a complete pre-workout nutrition system.
