GU Energy Original Sports Gel – Tri-Berry
The Original Sports Nutrition Energy Gel provides essential electrolytes and 100 calories in a portable packet. It uses a dual source of maltodextrin and fructose to optimize absorption via non-competing pathways, supporting energy during running, cycling, hiking, or skiing. Recommended use is one packet before activity and another every 45 minutes during exercise, making it a staple for mixed-effort triathlon sessions where steady fueling matters.
Huma Chia Energy Gel – Variety Pack
Hüma Chia Energy Gel emphasizes real-food ingredients with fruit puree, chia seeds, and brown rice syrup. It is gluten-free, dairy-free, vegan-friendly, and designed to be stomach-friendly, reducing common GI issues during long efforts. Tasting good and easy to digest, it suits triathletes who prefer a more natural fueling approach without dextrose or maltodextrin heavy profiles.
Neversecond C30+ Energy Gel with Caffeine – Berry
Neversecond C30+ combines 30g of fast-absorbing energy with 75mg of caffeine and 200mg of sodium. The gel’s thin consistency facilitates easy consumption, with electrolytes aiding hydration and a mild berry flavor to reduce gastric distress. It’s positioned for endurance running, ultramarathons, or long cycling sessions where sustained alertness and hydration are valuable.
GU Energy Roctane Ultra Endurance Gel
Roctane Ultra Endurance Gel adds 1425mg of amino acids to help reduce muscle damage and mental fatigue during long efforts. It provides 100 calories with electrolytes and uses dual-source carbs (maltodextrin and fructose) for efficient energy delivery. This gel targets triathletes facing extended workouts or races choosing a higher-performance formula for endurance.
MAURTEN Gel 100 Energy Gel
Gel 100 employs patented hydrogel technology to deliver carbohydrates directly from the stomach to the intestine. Each serving provides 25g of carbohydrates, enabling high hourly carbohydrate intake (up to 100g per hour) with a focus on stomach comfort and rapid absorption. It suits endurance athletes who prioritize minimal GI distress and steady fueling during long swims, rides, or runs.
Neversecond C30 Fruit Punch Energy Gel
Neversecond’s C30 Fruit Punch variant offers a similar gel with 30g of fast-absorbing energy, 200mg of sodium, and a lightly flavored profile designed to minimize gastric distress. It is suitable for endurance athletes seeking a reliable energy source with a hydration-friendly formula, adaptable to a race-day fueling plan for long-distance triathlons.
UCAN Edge Energy Gel Shots – Strawberry Banana
UCAN Edge Energy Gel Shots emphasize a sugar-free, vegan, and keto-friendly approach with LIVSTEADY, a plant-based fuel. This option aims to prevent energy crashes and suit athletes who want stable energy levels across workouts and races. It can be used as pre-, intra-, or post-workout fuel, making it versatile for triathlon training plans that include varied intensities.
Buying Guide: Key Purchase Considerations for Triathlon Fuel Gels
Carbohydrate profile and absorption: Look for gels with balanced glucose-to-fructose ratios or innovative delivery systems (like hydrogel) to maximize absorption and minimize GI distress during the swim, bike, and run transitions.
Electrolytes and sodium: Adequate sodium helps with fluid delivery and prevents dehydration during long sessions. For hot or humid conditions, prioritize gels with electrolytes alongside carbohydrates.
Flavor and texture: A gel that is easy to swallow and tastes acceptable reduces the risk of gastric issues during competition. Thin, pourable textures can help with race-day swallowing without extra fluids.
Amino acids and protein: Some gels include amino acids to support muscle maintenance and fatigue reduction during ultra-distance events. Consider these if you expect long, demanding efforts.
Ingredients and dietary needs: If you prefer real-food ingredients, vegan or dairy-free options, or gluten-free formulas, choose accordingly. Some athletes may benefit from non-traditional bases like chia or fruit puree.
Volume and portability: For triathlons, compact packets that fit in a jersey pocket or race belt help with quick access during transitions or on the bike.
Flavors and tolerances: Consider caffeine content and flavor intensity. Caffeine can boost alertness for late race segments but may upset sensitive stomachs in some athletes. Plan caffeine use around the race schedule.
Practical testing: Always test gels in training under similar conditions to race day. This helps verify stomach tolerance, absorption timing, and hydration strategy without risking an event-day GI issue.
