Product Description
Sprint triathlon looks short on paper. It doesn't feel short when you're buried in the bike leg, heart rate maxed, trying to hold the pace you need for a fast run split. You've probably pieced together your own race-day nutrition, a random gel, a hydration mix you've never tested at speed, nothing planned for recovery, and wondered why you felt flat crossing the finish. Here's what most athletes don't realize: in a Zone 5 effort across three disciplines, the biggest fueling mistakes happen before you even hit the water.
The Supertri Race Pack is the exact race-day nutrition kit curated by The Feed: seven products, four categories, one complete protocol from the night before to the finish line.
Built for Two Transitions, Not Just One Discipline
Most race-day packs are built for a single sport. This one is designed around the specific demands of swim-bike-run at race pace: fast-absorbing carbs for explosive bike output, sodium that scales with your sweat rate, and recovery tools timed to the gaps Supertri actually gives you.
The Night-Before Protocol Most Athletes Skip
Amacx Cherry Juice+ is a 500mL ready-to-drink bottle with 125mg anthocyanins, the anti-inflammatory compounds that give tart cherries their deep red color, plus 30g of carbs to prime your glycogen. Research shows these compounds reduce muscle damage when taken 12–24 hours before competition. The race starts the night before, not at the starting horn.
Sodium That Actually Matches Your Sweat Rate
Mortal Hydration is the first hydration mix to offer a range of sodium, 450mg in the regular flavors and up to ~900mg in the salty flavors, so you can match your electrolyte intake to your actual sweat loss, not a one-size number someone else picked for you.
Each GU Energy Gel delivers 22g of fast-absorbing carbs, 60mg of sodium, and 450mg of amino acids, which are the building blocks that slow muscle breakdown during hard back-to-back efforts. The bike leg is your fueling window; the GU gels are built to deliver 60–90g of carbs per hour without overwhelming your gut even when your heart rate is pinned. The three Foundation single serves round out the protocol with key recovery nutrients before and after the race.
Night Before: Drink the Amacx Cherry Juice+ and take one Foundation serving with your evening meal.
Race Morning: Mix one Mortal Hydration serving into 500mL of water 60–90 minutes before your start. Take a second Foundation serving with breakfast. Never try a new hydration flavor for the first time on course.
On Course: Take your first GU Energy Gel 10–15 minutes before the swim. Your second gel goes on the bike every 30 minutes. Use that fueling window.
Pro tip: Practice with the GU gels in at least one brick session before race day. Knowing how your stomach handles them at race intensity is the difference between confidence and guesswork.
Post-Race: Mix your remaining Mortal packet immediately after finishing, and take your last Foundation serving within 30 minutes. Don't waste the most important nutritional window of your race on water and a banana.
Beth Potter, two-time Olympic Gold Medalist and Supertri athlete, puts it directly: staying hydrated and loaded the day before is where most athletes lose the race before it starts. The elites racing Austin to Long Beach have dialed in exactly this protocol. Now you have the same kit.
This isn't just another race-day bundle. This is Zone 5 fuel for Zone 5 problems: seven products, every phase covered, nothing left to chance.
What Is the Supertri Race Pack?
The Supertri Race Pack is The Feed's official race nutrition kit for Supertri Series athletes: seven products covering every phase of competition from the night before through post-race recovery. GU Energy Gels (22g carbs, 60mg sodium, 450mg amino acids) handle on-course fueling, Mortal Hydration (450–900mg sodium) matches your sweat rate, Foundation single serves support muscle recovery, and Amacx Cherry Juice+ (125mg anthocyanins, 30g carbs, 500mL RTD) delivers the night-before anti-inflammatory protocol the best athletes in the sport don't skip.
After years of watching thousands of athletes order through The Feed, the pattern is impossible to miss. The ones who have a bad race almost always tell us the same thing afterward: they winged the nutrition. Grabbed whatever was at the expo, skipped hydration the night before, took a gel they'd never trained with. The ones who nail it? They had a protocol and they'd already tested every product in training. I built this pack so you don't have to figure that out the hard way. Everything in here has been tested by real athletes, in real races. It works. But only if you follow the protocol, not just the products.

Supertri Race Pack FAQ's
Everything you need to know about Supertri Race Pack.
The pack contains seven products across four categories:
GU Energy Gel (x2): 22g carbs, 60mg sodium, 450mg amino acids each.
Mortal Hydration Sampler Pack (x1): Multiple sodium options, 450mg or ~900mg per serving.
Foundation Single Serve (x3): Key amino acids and recovery nutrients per pouch.
Amacx Cherry Juice+ (x1): 500mL RTD, 125mg anthocyanins, 30g carbs.
Together they cover every phase of race-day nutrition from the night before through post-race recovery.
The night before your race, with your evening meal. The anti-inflammatory compounds in tart cherry, called anthocyanins, need 12–24 hours to peak in your system. Taking it the morning of the race is too late to get the full benefit. If your race is on a Sunday, drink it Saturday evening alongside one Foundation serving.
Take your first GU gel 10–15 minutes before the swim start, with a small amount of water. Take your second gel on the bike, targeting every 30 minutes of effort. The bike leg is your primary fueling window in sprint triathlon. Never take a gel for the first time on race day — practice with them in at least one brick session beforehand.
Mortal Hydration replaces the minerals your muscles need to keep firing during effort: primarily sodium, potassium, and magnesium. The sampler pack includes multiple flavors at different sodium levels so you can find what works before you commit. If you're a heavy sweater, sweat visibly on your skin, or race in hot conditions, start with the higher-sodium option. If you're a lighter sweater or racing in cooler weather, the standard 450mg option is a good starting point.
Foundation delivers amino acids, including the branched-chain amino acids that slow muscle breakdown during hard efforts, along with recovery-supporting nutrients. Take one serving the night before with your Amacx Cherry Juice+, a second serving at breakfast on race morning, and your third serving within 30 minutes of finishing. That post-race window is the most important one for recovery — don't skip it.
The pack is optimized for sprint triathlon, which runs up to approximately 90 minutes of racing. The night-before protocol with Amacx Cherry Juice+ and Foundation carries over perfectly to any distance. For Olympic distance or longer, you'll need additional on-course carbohydrates beyond the two GU gels included here. A good rule of thumb is one gel per 30–45 minutes of effort at race intensity.
