Cycling Gels & Drink Mixes | Threshold Cycling

High-Carb Cycling Energy Gels, Hydration Drink Mixes & Endurance Fuel

Unlock sustained endurance wattage, eliminate mid-ride bonking, and accelerate post-ride recovery with elite sports nutrition from Threshold Cycling. Modern endurance science has transformed on-the-bike fueling: athletes no longer settle for minimal hydration—they systematically fuel with 60 to 120 grams of carbohydrates per hour to preserve muscle glycogen, stabilize blood glucose, and crush personal records on gravel, road, and gran fondo courses.

As an Official US Authorized Retailer for Carbs Fuel, Untapped, and Liquid I.V., our collection delivers the most advanced dual-transporter carbohydrate formulations and pure whole-food fueling solutions in the sport:

  • Dual-Transporter 1:0.8 Ratio (Carbs Fuel): Combines maltodextrin (SGLT1 transporter) and fructose (GLUT5 transporter) in an optimized 1:0.8 ratio, unlocking up to 120g of absorbable carbs per hour without bloating or gastrointestinal distress.
  • Double-Density 50g Gels: Packing 50 grams of carbohydrates into a single semi-fluid liquid pouch, Carbs Fuel eliminates the need to carry 4–5 sticky standard gels every hour.
  • High-Sodium Hydration (450–500mg): High-sweat electrolyte replacement that prevents cramping and sustains cellular fluid balance in hot conditions.
  • Pure Vermont Maple Whole Food (Untapped): 100% pure organic Grade A maple syrup providing low-glycemic, unrefined natural energy that is exceptionally gentle on sensitive stomachs.

Tactical Hourly Fueling Protocols: How Much Should You Consume?

Match your carbohydrate intake to your ride duration and intensity:

  • The 60g/hr Base Protocol (Rides Under 2 Hours): Consume one Carbs Fuel 50g Energy Gel or sip one bottle of light hydration mix every hour. Keeps blood glucose steady during tempo intervals without overloading digestion.
  • The 90g/hr Endurance Protocol (2 to 4 Hours / Gran Fondos): Drink one bottle of Carbs Fuel Drink Mix (75g) plus one Untapped Maple Gel (26g) every hour, or alternate between a 50g gel and liquid carbs every 30–40 minutes.
  • The 120g/hr Elite Race Protocol (4+ Hours / Unbound Gravel & Centuries): Pair one bottle of Carbs Fuel Drink Mix (75g) with one Carbs Fuel 50g Energy Gel each hour. This delivers an exact 125g/hr dual-transporter intake for maximum oxidative power in grueling endurance events.

Frequently Asked Questions

How many grams of carbohydrates should I consume per hour during cycling?

Optimal carbohydrate intake depends on the duration and intensity of your ride:

  • Under 2 Hours (Standard Training / Group Rides): Aim for 30–60 grams of carbs per hour. One standard 50g Carbs Fuel gel or one bottle of light drink mix is sufficient to sustain blood glucose and delay fatigue.
  • 2 to 4 Hours (Hard Long Rides / Gran Fondos): Target 60–90 grams of carbs per hour. Combining one bottle of Carbs Fuel Drink Mix (75g) per hour, or sipping electrolytes while consuming one 50g gel every 45 minutes, maintains high glycogen levels.
  • 4+ Hours & Competitive Racing (Gravel, Crits, Centuries): Elite athletes target 90–120 grams of carbs per hour. You can hit 125g/hr seamlessly by pairing one bottle of Carbs Fuel Drink Mix (75g) with one Carbs Fuel 50g Energy Gel every hour.

What is the advantage of the 1:0.8 Maltodextrin to Fructose carbohydrate ratio?

The human body uses two distinct intestinal transporters to absorb carbohydrates from the gut into the bloodstream:

  • SGLT1 Transporters (Glucose / Maltodextrin): Can only absorb approximately 60 grams of glucose per hour before becoming completely saturated. Consuming more than 60g of glucose alone leads to gut pooling, bloating, and severe nausea.
  • GLUT5 Transporters (Fructose): Absorb carbohydrates via an entirely separate, non-competing pathway. Adding fructose in an optimal 1:0.8 maltodextrin-to-fructose ratio allows your body to absorb an additional 30–60 grams per hour.
  • Maximum Energy with Zero GI Distress: Carbs Fuel's 1:0.8 formulation delivers up to 120g/hr of rapidly oxidizable carbohydrates directly to working muscles with virtually zero stomach cramping or distress.

Why do Carbs Fuel 50g energy gels have twice the carbohydrates of standard gels?

Traditional energy gels (like standard GU or Maurten 100) only provide 20 to 25 grams of carbohydrates per packet. If your target is 90 to 100 grams per hour, you would have to carry, open, and swallow 4 to 5 sticky packets every 60 minutes—cluttering your jersey pockets with empty trash and causing flavor fatigue.

Carbs Fuel solves this with a high-density 50-gram formula: Just one ergonomic packet delivers the carbohydrate equivalent of two traditional gels. With a smooth, semi-fluid liquid consistency that requires no extra water to swallow, it cuts your pocket bulk in half and simplifies on-the-bike fueling math.

When should I choose Untapped pure maple syrup over maltodextrin-based gels?

Untapped Maple Energy Gels are crafted from 100% pure organic Grade A Vermont maple syrup. They are the ideal choice for endurance cyclists who prioritize whole-food nutrition:

  • All-Natural & Unrefined: Contains zero synthetic maltodextrin, artificial preservatives, thickeners, or coloring agents.
  • Gentle on the Stomach: Maple syrup has a naturally low glycemic index and a balanced blend of sucrose, glucose, and fructose that is exceptionally easy to digest, making it a favorite for athletes with sensitive stomachs or IBS.
  • Rich in Natural Electrolytes & Minerals: Naturally provides potassium, zinc, manganese, calcium, and over 50 antioxidants that support muscular function and recovery.
