What really matters in a 70.3 nutrition strategy?
A nutrition strategy for a 70.3 usually includes:
• 60 to 90 g of carbohydrates per hour
• structured hydration
• sodium replacement
• strategic caffeine intake
The goal is to maintain stable blood glucose levels, preserve muscle glycogen and avoid performance drops during the final part of the race.
How many carbohydrates should you consume during a 70.3?
In endurance races like a 70.3, current recommendations usually range between 60 and 90 g of carbohydrates per hour.
To reach this intake, many athletes use gels with multiple carbohydrate sources, such as maltodextrin, fructose and isomaltulose, a combination found in Z2’s Every Day, Game Day and Load Up lines.
In practice, a common strategy includes:
• 1 gel before the start
• 1 gel every 25 to 30 minutes
• adjustments based on weather conditions and gastrointestinal tolerance
Sodium replacement during a 70.3
Sodium loss through sweat can vary greatly between athletes, especially during long races in hot conditions.
For this reason, modern endurance strategies include structured electrolyte replacement throughout the race.
In many cases, athletes consume between 500 mg and 1000 mg of sodium per hour.
Products such as SaltZ 500 mg and SaltZ 1000 mg help individualize electrolyte replacement according to sweat rate, temperature and race duration.
How to use caffeine strategically?
Caffeine is usually used more frequently during the second half of the race, especially during the run.
Caffeinated gels, such as Z2’s Game Day line, may help maintain focus, perceived effort and intensity during moments of greater fatigue.
Most common mistakes during a 70.3
Not testing the strategy beforehand
Every nutrition strategy should be tested during long training sessions to reduce gastrointestinal risk.
Consuming less carbohydrate than necessary
Many athletes reduce intake due to fear of gastrointestinal discomfort, increasing the risk of performance decline later in the race.
Neglecting hydration and electrolytes
Hydration without proper sodium replacement may compromise performance during long endurance events.
Conclusion
An effective nutrition strategy for a 70.3 should be individualized, practiced and adjusted according to race duration, weather conditions and athlete tolerance.
Modern endurance strategies prioritize carbohydrate intake per hour, structured hydration, electrolyte replacement and smart caffeine use. Products such as Every Day, Game Day, Load Up and SaltZ by Z2 help athletes create more practical and efficient protocols for training and racing.
