Product Description
You try a new gel on race morning, and your stomach quits at mile 10. Here's what most athletes don't realize: fueling is personal, and the only way to find what fits you is to test it in training. Committing to a full box of something you've never used is a gamble.
The First Endurance Tryout Packs put Liquid Shot and EFS Drink Mix in your hands in small amounts: the 9-Pack gives you nine Liquid Shots (three each of Kona Mocha with caffeine, Vanilla, and Wild Berry), and the Liquid Shot + EFS Pack pairs three Liquid Shots with two Lemon Lime EFS singles.
Fast Fuel, No Thickeners – Each Liquid Shot delivers 110 calories and 30g of fast-acting carbohydrate with no gums to slow it down, so it clears your stomach quickly and reaches your muscles when you need it.
Three Flavors, Zero Guesswork – Every pack includes Kona Mocha, Vanilla, and Wild Berry, so you learn which one you still want at hour four. Kona Mocha has caffeine, so save it for when you want the lift.
Built to Work Together – In the Liquid Shot + EFS Pack, EFS Drink Mix handles your hourly hydration while Liquid Shot covers the surges, with no ingredient overlap between them.
Liquid Shot is isotonic, meaning it matches the concentration of your body's fluids, so carbohydrate leaves your stomach faster and your gut stays calmer. Many traditional gels use gums and thickeners that slow absorption. EFS delivers 30g of carbohydrate plus all five electrolytes, the minerals that keep your muscles firing: sodium, potassium, chloride, calcium, and magnesium. Replacing them as you sweat helps you hold off cramping.
How to Use First Endurance Tryout Packs
Liquid Shot: Take one gel every 30 to 60 minutes, depending on your fueling needs.
EFS Drink Mix (Liquid Shot + EFS Pack): Mix one serving in 500 to 700 ml of water every hour, and repeat as needed.
Pro Tip: Test one flavor per session and note how your gut responds.
First Endurance designs Liquid Shot and EFS as a complementary system for endurance athletes who need steady carbohydrate and electrolytes over long efforts.
Stop guessing on race day. Get your fueling dialed in training.
