"My performance has been taken to the next level thanks to First Endurance. Since switching to FE in 2019, I have been able to absorb more carbohydrates and fluids during races and training. It gives me confidence on the start line knowing I have a leg up on the competition with the best sports nutrition products available."
-Jackson Laundry (Ironman 70.3 Champion)
PreRace is a revolutionary pre-exercise supplement developed to provide endurance athletes with a potent mental and cardiac jump-start prior to races or workouts. The Pre-race formula provides all the necessary ingredients needed to increases mental stamina, increases time to exhaustion, increases maximum workload, improves mental clarity and increases oxygenation of muscles.
Features include caffeine, taurine, qurcetin and a proprietary neuro-stimulant blend. PreRace comes as a flavor free powder which can be added to any pre-exercise or during exercise drink, like EFS.
Improves Cardiac Output & Performance
PreRace is designed to stimulate the Nitric Oxide (NO) system, increase time to exhaustion and improve performance. NO improves blood flow, clears lactate and delivers more nutrients to working muscles. Citrulline Malate and Taurine have been shown to enhance cardiac output leading to numerous endurance enhancements.
Increases Mental Clarity & Focus
This Pre-Exercise supplement also improves cognitive function and mental clarity through CNS stimulation. PreRace is formulated with a proprietary Neuro-stimulant blend that contains diMethyl amino ethanol (DMAE), metabromine and catechin to improve mental acuity. This special Neuro-stimulant blend works synergistically with 200mg of caffeine and quercetin to improve time to exhaustion and increase maximum workload.
Warning: Consult your health care professional before use. Discontinue use if dizziness, sleeplessness, tremors, nervousness, headaches, heart palpitations or tingling sensations occur. Not intended for use by persons under the age of 18. Keep out of the reach of children. Begin use with one half the recommended dose to assess your tolerance. Improper use may be hazardous to a person’s health.
