A <strong>pre-race shot<\/strong> gives you the full dose of performance ingredients in 60 ml of liquid: nothing to mix, nothing to measure, no gritty beta-alanine clumps, and almost no volume in the gut when the gun goes. Liquid ingredients are already dissolved, so absorption begins as soon as the vial is down \u2013 that is why SCN\u2122 recommends taking Race Day just 10\u201315 minutes before warm-up instead of the 45\u201360 minutes most powders require.<\/p>\n<p>Most pre-workouts on the market were designed for a 60-minute strength session: a huge stimulant spike, a pump, and a crash. Endurance athletes need something different \u2013 <strong>steady energy, better oxygen delivery, delayed muscle acidosis and a controlled stimulant curve<\/strong> that lasts as long as the race does.

Caffeine taken in solution appears in the blood within minutes and reaches peak concentration roughly 30\u201360 minutes after ingestion<sup>[1]<\/sup> \u2013 so a vial taken 10\u201315 minutes before warm-up means caffeine is peaking exactly when the race or main set gets hard. Caffeine&#8217;s half-life of several hours then keeps the stimulant effect working through a two-hour-plus event.<sup>[1]<\/sup><\/p>\n<p>The energy side runs on a different clock: Palatinose\u2122 (isomaltulose) is digested slowly, releasing glucose over roughly two hours while blood sugar stays stable and fat oxidation stays higher than with fast sugars.<sup>[2,3]<\/sup> Together, the two curves \u2013 fast-rising stimulants and slow-releasing carbohydrate \u2013 are what give Race Day its long, even window of action.<\/p>\n<div class=\"rd-note\"><strong>Caffeine content:<\/strong> one full 60 ml vial provides approximately 360 mg of caffeine (250 mg caffeine anhydrous + ~110 mg from guarana extract 22%). This is a high-caffeine product. For a 70 kg athlete, a full vial sits at the upper end of the 3\u20136 mg\/kg range recommended by the International Society of Sports Nutrition;<sup>[1]<\/sup> half a vial (~180 mg) is the right starting point for lighter, amateur or caffeine-sensitive athletes. Not recommended for children, pregnant or breast-feeding women, or people sensitive to caffeine.<\/div>\n<p><!-- ================= INGREDIENTS ================= --><\/p>\n<h2>Every ingredient in Race Day \u2013 and why it is there<\/h2>\n<p>All 13 actives are written out below in full. Doses are per 60 ml vial.<\/p>\n<div class=\"rd-ing\">\n<h3>Palatinose\u2122 (isomaltulose) <span class=\"rd-dose\">6,000 mg<\/span><\/h3>\n<p>Palatinose\u2122 is a low-glycaemic carbohydrate made from sugar beet sucrose. The glucose\u2013fructose bond is rearranged from the \u03b1-1,2 linkage of sucrose into a much more stable \u03b1-1,6 linkage, so our digestive enzymes break it down four to five times more slowly. The result is full carbohydrate energy (4 kcal\/g) released gradually, a low and stable blood glucose response, and no insulin spike-and-crash before the start.<sup>[2]<\/sup><\/p>\n<p>In endurance studies, isomaltulose before exercise kept blood glucose steadier and <strong>maintained higher fat oxidation during prolonged cycling<\/strong> than maltodextrin or sucrose, sparing glycogen for later in the effort.<sup>[2,3]<\/sup> It is vegan, non-GMO, mildly sweet (about half the sweetness of sugar) and tooth-friendly.<\/p>\n<ul class=\"rd-list\">\n<li>Balanced, sustained energy supply \u2013 stretching the power curve<\/li>\n<li>Low glycaemic response \u2013 no pre-start sugar crash<\/li>\n<li>Supports fat oxidation and glycogen sparing during exercise<\/li>\n<li>Gentle on the stomach at race intensity<\/li>\n<\/ul>\n<\/div>\n<div class=\"rd-ing\">\n<h3>L-Citrulline Malate 1:1 <span class=\"rd-dose\">3,000 mg<\/span><\/h3>\n<p>L-citrulline is one of the three amino acids of the urea cycle, alongside L-arginine and L-ornithine. Taken orally it bypasses the liver and is converted to arginine in the kidneys, raising plasma arginine \u2013 and therefore nitric oxide production \u2013 more effectively than arginine itself. Nitric oxide relaxes blood vessels, improving blood flow and oxygen delivery to working muscle. Citrulline also accelerates ammonia clearance, one of the metabolic by-products that promotes fatigue in long efforts.<\/p>\n<p>Citrulline malate 1:1 binds each citrulline to a molecule of malic acid, an intermediate of the Krebs cycle that supports aerobic ATP production. Meta-analyses of placebo-controlled trials show citrulline malate <strong>increases repetitions to fatigue in high-intensity exercise<\/strong><sup>[4]<\/sup> and <strong>significantly lowers perceived exertion and muscle soreness at 24\u201348 hours<\/strong> after exercise.<sup>[5]<\/sup> Race Day combines citrulline malate with arginine HCl and arginine AKG to feed the nitric oxide pathway from both ends.<\/p>\n<\/div>\n<div class=\"rd-ing\">\n<h3>Beta-Alanine <span class=\"rd-dose\">3,000 mg<\/span><\/h3>\n<p>Beta-alanine is the rate-limiting precursor of carnosine, the dipeptide (beta-alanine + histidine) that buffers hydrogen ions inside the muscle fibre. When intensity rises above threshold, acidosis builds and contraction fails \u2013 carnosine delays that point. The International Society of Sports Nutrition position stand concludes that beta-alanine <strong>improves exercise capacity and performance, especially in efforts lasting 1\u20134 minutes and in high-intensity endurance events<\/strong>.<sup>[6]<\/sup> A meta-analysis across 40 studies confirmed the greatest benefit for exercise in the 30-second to 10-minute range \u2013 exactly the surges, climbs and finishing kicks that decide endurance races.<sup>[7]<\/sup><\/p>\n<ul class=\"rd-list\">\n<li>Buffers muscle acidosis and delays the burn<\/li>\n<li>Supports anaerobic and aerobic endurance<\/li>\n<li>Supports power output in surges and sprints<\/li>\n<li>Lets you hold a harder pace for longer<\/li>\n<\/ul>\n<p class=\"rd-ref\">Note: a tingling sensation (paraesthesia) 15\u201320 minutes after ingestion is a normal, harmless effect of beta-alanine. For the full chronic benefit, beta-alanine works best with daily loading \u2013 Race Day&#8217;s 3,000 mg on training and race days adds to the carnosine stores you build with daily use of other SCN\u2122 endurance products.<\/p>\n<\/div>\n<div class=\"rd-ing\">\n<h3>L-Arginine HCl <span class=\"rd-dose\">2,500 mg<\/span> &nbsp;+&nbsp; Arginine Alpha-Ketoglutarate (AAKG) <span class=\"rd-dose\">1,000 mg<\/span><\/h3>\n<p>L-arginine is the direct substrate for nitric oxide synthase \u2013 the enzyme that produces nitric oxide. Race Day uses two forms: the hydrochloride salt for rapid absorption, and arginine bound to alpha-ketoglutarate (AKG), a Krebs-cycle intermediate. AKG is one of the body&#8217;s key nitrogen carriers; it participates in energy production in the Krebs cycle and in the metabolism of proline and hydroxyproline, the amino acids of type I collagen.<\/p>\n<p>Combining arginine with citrulline is deliberate: citrulline sustains plasma arginine over hours, while direct arginine provides the immediate substrate. Together they support blood flow, oxygen and nutrient delivery during the effort and help the heart rate settle faster between intervals and after the finish.<\/p>\n<\/div>\n<div class=\"rd-ing\">\n<h3>Taurine <span class=\"rd-dose\">1,250 mg<\/span><\/h3>\n<p>Taurine is a sulphur-containing amino acid concentrated in skeletal and cardiac muscle, where it regulates calcium handling in the contracting fibre, cell hydration and osmotic balance, and acts as an antioxidant. A meta-analysis of endurance trials found that a <strong>single dose of 1\u20136 g taurine taken 1\u20133 hours before exercise improved endurance performance<\/strong> \u2013 time to exhaustion and time-trial performance \u2013 in trained and untrained participants.<sup>[8]<\/sup><\/p>\n<ul class=\"rd-list\">\n<li>Supports cellular hydration and electrolyte balance<\/li>\n<li>Supports calcium regulation and muscle contraction<\/li>\n<li>Supports central nervous system function and focus<\/li>\n<li>Antioxidant support during intense exercise<\/li>\n<\/ul>\n<\/div>\n<div class=\"rd-ing\">\n<h3>Glucuronolactone <span class=\"rd-dose\">1,250 mg<\/span><\/h3>\n<p>D-glucurono-\u03b3-lactone is a natural metabolite of glucose, present in the body in equilibrium with glucuronic acid, which participates in phase II detoxification (glucuronidation). It is a classic energy-drink ingredient, and the research on it comes mostly from that context: when healthy volunteers were given a drink combining glucuronolactone, caffeine and taurine, they showed <strong>improvements in aerobic and anaerobic performance, reaction time, concentration and memory<\/strong> compared with placebo.<sup>[9]<\/sup> Pre-workout studies with the same combination reported more total repetitions performed in training.<sup>[10]<\/sup> In Race Day it is paired with exactly those partners \u2013 caffeine, taurine and citrulline \u2013 for its synergistic effect on physical and mental performance.<\/p>\n<\/div>\n<div class=\"rd-ing\">\n<h3>Caffeine Anhydrous <span class=\"rd-dose\">250 mg<\/span> &nbsp;+&nbsp; Guarana Liquid Extract 22% <span class=\"rd-dose\">500 mg<\/span><\/h3>\n<p>Caffeine is the most studied legal ergogenic aid in sport. The 2021 International Society of Sports Nutrition position stand concludes that <strong>3\u20136 mg\/kg of caffeine consistently improves endurance performance, lowers rating of perceived exertion and enhances alertness and vigilance<\/strong>.<sup>[1]<\/sup> It works mainly through adenosine-receptor antagonism in the central nervous system \u2013 effort feels easier \u2013 and supports fat mobilisation, which can spare glycogen in longer events.<\/p>\n<p>Guarana (<em>Paullinia cupana<\/em>), the Amazonian seed also known as Brazilian cocoa, contains caffeine naturally bound to tannins and polyphenols, alongside theobromine and theophylline. Its caffeine is released more gradually than pure caffeine anhydrous, so the two sources together give Race Day a <strong>fast rise and a longer plateau<\/strong> rather than a single spike. Guarana is studied for delaying fatigue, supporting aerobic capacity and improving mental alertness.<\/p>\n<ul class=\"rd-list\">\n<li>Lower perceived effort at a given pace<\/li>\n<li>Supports endurance and time-trial performance<\/li>\n<li>Supports fat oxidation and glycogen sparing<\/li>\n<li>Sharper focus, alertness and reaction time<\/li>\n<\/ul>\n<p class=\"rd-ref\">Competition note: caffeine was removed from the WADA Prohibited List in 2004 and remains on the Monitoring Program only. Total caffeine per full vial \u2248 360 mg.<\/p>\n<\/div>\n<div class=\"rd-ing\">\n<h3>Vitamin C (ascorbic acid) <span class=\"rd-dose\">500 mg<\/span><\/h3>\n<p>Intense endurance exercise generates free radicals and temporarily suppresses immune defence. Vitamin C contributes to the protection of cells from oxidative stress, to normal immune function during and after intense physical exercise, to normal collagen formation for tendons, ligaments and cartilage, to normal energy-yielding metabolism, to reduced tiredness and fatigue, and it increases iron absorption \u2013 important for oxygen transport in endurance athletes.<\/p>\n<\/div>\n<div class=\"rd-ing\">\n<h3>Niacin (vitamin B3) <span class=\"rd-dose\">150 mg<\/span><\/h3>\n<p>Niacin is the precursor of NAD\u207a and NADP\u207a, the coenzymes at the centre of every energy-producing pathway in the cell \u2013 glycolysis, the Krebs cycle and the electron transport chain. The body cannot store it, so athletes with high energy turnover need constant replenishment. Niacin contributes to normal energy-yielding metabolism, normal functioning of the nervous system, normal psychological function and the reduction of tiredness and fatigue.<\/p>\n<p class=\"rd-ref\">Note: at this dose, nicotinic acid may cause a temporary, harmless flushing or warmth of the skin in some people.<\/p>\n<\/div>\n<div class=\"rd-ing\">\n<h3>Vitamin B1 (thiamine) <span class=\"rd-dose\">39.5 mg<\/span><\/h3>\n<p>Thiamine, as thiamine pyrophosphate, is the coenzyme that converts pyruvate into acetyl-CoA \u2013 the gateway from carbohydrate into the Krebs cycle. The more carbohydrate you burn, the more thiamine you use. Thiamine contributes to normal energy-yielding metabolism, normal functioning of the nervous system, normal psychological function and normal heart function. Research on thiamine and exercise suggests improved carbohydrate metabolism with lower lactate and ammonia accumulation during exercise.<\/p>\n<\/div>\n<div class=\"rd-ing\">\n<h3>Vitamin B6 (pyridoxine) <span class=\"rd-dose\">9.52 mg<\/span><\/h3>\n<p>Vitamin B6 is a coenzyme in over 100 reactions, including the breakdown of muscle glycogen (glycogen phosphorylase) and amino-acid metabolism \u2013 both heavily used in endurance exercise. It is water-soluble and lost in sweat and urine, so losses rise with training volume. Vitamin B6 contributes to normal energy-yielding metabolism, normal protein and glycogen metabolism, normal red blood cell formation, normal functioning of the nervous system, normal psychological function, normal immune function and the reduction of tiredness and fatigue.<\/p>\n<\/div>\n<p><!-- ================= FULL TABLE ================= --><\/p>\n<h2>Full formula \u2013 per 60 ml vial<\/h2>\n<table class=\"rd-table\">\n<tr>\n<th>Active ingredient<\/th>\n<th>Per vial (60 ml)<\/th>\n<th>Per half vial (30 ml)<\/th>\n<\/tr>\n<tr>\n<td>Palatinose\u2122 (isomaltulose)<\/td>\n<td>6,000 mg<\/td>\n<td>3,000 mg<\/td>\n<\/tr>\n<tr>\n<td>L-Citrulline Malate 1:1<\/td>\n<td>3,000 mg<\/td>\n<td>1,500 mg<\/td>\n<\/tr>\n<tr>\n<td>Beta-Alanine<\/td>\n<td>3,000 mg<\/td>\n<td>1,500 mg<\/td>\n<\/tr>\n<tr>\n<td>L-Arginine HCl<\/td>\n<td>2,500 mg<\/td>\n<td>1,250 mg<\/td>\n<\/tr>\n<tr>\n<td>Taurine<\/td>\n<td>1,250 mg<\/td>\n<td>625 mg<\/td>\n<\/tr>\n<tr>\n<td>Glucuronolactone<\/td>\n<td>1,250 mg<\/td>\n<td>625 mg<\/td>\n<\/tr>\n<tr>\n<td>Arginine Alpha-Ketoglutarate (AAKG)<\/td>\n<td>1,000 mg<\/td>\n<td>500 mg<\/td>\n<\/tr>\n<tr>\n<td>Vitamin C<\/td>\n<td>500 mg<\/td>\n<td>250 mg<\/td>\n<\/tr>\n<tr>\n<td>Guarana Liquid Extract 22% (\u2248110 mg caffeine)<\/td>\n<td>500 mg<\/td>\n<td>250 mg<\/td>\n<\/tr>\n<tr>\n<td>Caffeine Anhydrous<\/td>\n<td>250 mg<\/td>\n<td>125 mg<\/td>\n<\/tr>\n<tr>\n<td>Niacin (vitamin B3)<\/td>\n<td>150 mg<\/td>\n<td>75 mg<\/td>\n<\/tr>\n<tr>\n<td>Vitamin B1 (thiamine)<\/td>\n<td>39.5 mg<\/td>\n<td>19.75 mg<\/td>\n<\/tr>\n<tr>\n<td>Vitamin B6 (pyridoxine)<\/td>\n<td>9.52 mg<\/td>\n<td>4.76 mg<\/td>\n<\/tr>\n<\/table>\n<p><strong>Other ingredients:<\/strong> purified water, citric acid, sorbitol, natural flavour (peach), sucralose.<\/p>\n<p><strong>Pack:<\/strong> 12 vials \u00d7 60 ml per box. <strong>Flavour:<\/strong> Peach.<\/p>\n<p><!-- ================= DIRECTIONS ================= --><\/p>\n<h2>How to use your pre-race shot<\/h2>\n<table class=\"rd-table\">\n<tr>\n<th>Athlete<\/th>\n<th>Dose<\/th>\n<th>Timing<\/th>\n<\/tr>\n<tr>\n<td>Lighter-weight or amateur athletes, first-time users, caffeine-sensitive<\/td>\n<td>30 ml (half vial)<\/td>\n<td>10\u201315 minutes before warm-up<\/td>\n<\/tr>\n<tr>\n<td>Heavier or professional athletes, experienced caffeine users<\/td>\n<td>60 ml (one vial)<\/td>\n<td>10\u201315 minutes before warm-up<\/td>\n<\/tr>\n<\/table>\n<ul class=\"rd-list\">\n<li>Shake gently before opening.

Unlike a powder, it needs no mixing and carries very little volume into the stomach. Race Day is a 60 ml pre-race shot built specifically for endurance sport, combining slow-release carbohydrate, nitric oxide precursors, a muscle buffer and a dual-source stimulant stack.<\/p>\n<\/details>\n<details>\n<summary>How long before my race should I take Race Day?<\/summary>\n<p>10\u201315 minutes before you start your warm-up. Because it is a liquid, absorption begins immediately; caffeine peaks around 30\u201360 minutes later, right as the race gets hard.<\/p>\n<\/details>\n<details>\n<summary>How long does the effect last?<\/summary>\n<p>Palatinose\u2122 releases energy over roughly two hours, and caffeine&#8217;s multi-hour half-life keeps the stimulant effect working across a two-hour-plus event. Most athletes describe a long, even window rather than a spike and crash.<\/p>\n<\/details>\n<details>\n<summary>How much caffeine is in one vial?<\/summary>\n<p>Approximately 360 mg per full vial (250 mg caffeine anhydrous plus about 110 mg from guarana). Half a vial provides around 180 mg. Start with half if you are new to it or sensitive to caffeine.<\/p>\n<\/details>\n<details>\n<summary>Will it upset my stomach before a race?<\/summary>\n<p>Race Day was designed to avoid exactly that: only 60 ml of liquid, no fast sugars, and Palatinose\u2122, which is gentle on digestion. As with any race nutrition, test it in training first.<\/p>\n<\/details>\n<details>\n<summary>Is Race Day legal in competition?<\/summary>\n<p>Yes. None of the ingredients appears on the WADA Prohibited List. Caffeine has been off the list since 2004. SCN\u2122 products are produced in a doping-free, cross-contamination-safe facility.<\/p>\n<\/details>\n<details>\n<summary>Can I use Race Day every day?<\/summary>\n<p>It is designed for races and key sessions. For everyday training we recommend building your base with daily-use SCN\u2122 endurance products and saving Race Day for the days that count \u2013 that also keeps your caffeine response sharp.<\/p>\n<\/details>\n<details>\n<summary>Is it vegan?<\/summary>\n<p>Yes \u2013 every ingredient in Race Day is suitable for vegans.<\/p>\n<\/details>\n<\/div>\n<p><!-- ================= BUY ================= --><\/p>\n<div id=\"rd-buy\" class=\"rd-hero rd-center\" style=\"margin-top:36px\">\n<h2 style=\"font-size:1.8em\">Race Day \u2013 12 \u00d7 60 ml Pre-Race Shots<\/h2>\n<p>Single box \u00b7 3 boxes with 10% discount \u00b7 6 boxes with 15% discount<\/p>\n<p><a class=\"rd-cta\" href=\"#\">Add to basket<\/a><\/p>\n<p style=\"font-size:.9em;color:#555\">Shipped from Europe \u00b7 Doping-free &amp; cross-contamination safe \u00b7 Worldwide delivery<\/p>\n<\/div>\n<p><!-- ================= REFERENCES ================= --><\/p>\n<div class=\"rd-ref\">\n<h3>Scientific references<\/h3>\n<ol>\n<li>Guest NS et al.
