tips

Test different consumption timings to find what works best for you., Ensure adequate hydration alongside gel use to prevent dehydration., Pair with electrolyte supplements to compensate for low sodium content., Practice gel consumption at race pace to mimic competitive conditions.

week 1

Start with one gel during a mid-length run or ride, twice a week, to assess tolerance.

week 2

Increase to two gels per session, focusing on longer workouts to simulate race conditions.

week 3

Incorporate gels into race-pace sessions, aiming for one gel every 30-45 minutes.

week 4

Conduct a full race-day simulation, using gels at planned intervals to ensure comfort and effectiveness.

In high temperatures (>25°C), the gel maintains its consistency without becoming overly liquid, ensuring easy consumption. In cold conditions (<5°C), it may thicken slightly but remains manageable. The gel does not freeze easily, which is advantageous for cold-weather events.

The gel comes with a tear notch for easy opening, allowing one-handed use. It fits well in running belts and cycling jerseys, though care should be taken to avoid sticky residue in pockets.

The packaging does not provide specific recyclability information, and there are no claims regarding sustainable sourcing or brand transparency.

• Electrolyte tablets for sodium replenishment during long events.
• Protein bars post-exercise for recovery and muscle repair.
• Hydration packs to ensure adequate fluid intake alongside gel use.

• The isotonic formula allows for rapid absorption without additional water, as per product claims.
• Maltodextrin is a glucose polymer that is quickly metabolized, providing fast energy.
• The gel's low sodium content necessitates additional supplementation for endurance events.
• Single-source carbohydrate limits absorption to SGLT1 pathways, capping intake at around 60g/hr.
