Axe Endurance
CARB
Whether you’re chasing a PR or grinding through a long training day, your body needs fast, efficient fuel. Axe & Sledge Endurance Carb Powder delivers 30g of carbohydrates in a proven 1:1 glucose-to-fructose ratio—the gold standard for rapid absorption and sustained energy. This dual-source approach maximizes carbohydrate uptake and oxidation, supplying consistent fuel to working muscles while minimizing the gut distress common with single-source carbs.
Each serving also provides 220mg of sodium to support hydration, fluid balance, and nutrient delivery as sweat losses climb. Lightly flavored to prevent flavor fatigue, this formula is built for runners, cyclists, triathletes, CrossFitters, and hybrid athletes who demand reliable energy—rep after rep, mile after mile.
30g of Carbohydrates for Sustained Performance
Dual-Source Energy for Faster Absorption and Output
Clean, Fast Fuel Built for Long Sessions and Race Day
Axe Endurance
HYDRATE
This formula is built around 1,000mg of sodium from sodium citrate and sea salt—the most critical electrolyte for endurance performance. This clinical dose supports fluid balance, improves sweat efficiency, and helps reduce cramping as training intensity and duration increase. To round out hydration support, we’ve added 25mg magnesium, 150mg potassium, and 30mg calcium to replenish key minerals lost through sweat while supporting muscle contraction and nerve signaling.
Lightly flavored for all-day use, this formula is designed to prevent flavor fatigue whether you’re mid-session or staying ahead of dehydration daily. A precise amount of added sugar enhances electrolyte and water absorption in the small intestine, helping you rehydrate faster and more efficiently when performance matters most.

Fast-Absorbing Hydration Without Flavor Fatigue
Owner / Founder
BOBBY DAUTRICH
Bobby Dautrich is the co-founder of Axe & Sledge Supplements and an endurance athlete whose personal journey reshaped everything. Bobby has competed in numerous Ironman events and qualified for the Ironman World Championships. Along the way, he tested nearly every endurance product on the market and grew frustrated by products that overpromised and underdelivered. That firsthand experience is what led him to create the Axe & Sledge Endurance line: a no-nonsense, performance-driven collection of products built to fuel long training sessions, support recovery, and give endurance athletes exactly what they need.
