Caffeine consumption of 3-6 mg/kg body weight, taken 60 minutes before exercise, enhances endurance, alertness, and perceived effort in cycling.
Take 3-6 mg of caffeine per kg of body weight about 60 minutes before your ride. This is one of the most effective legal ways to boost endurance and focus. Start with the lower end if you are sensitive.

More from this paper
- Carbohydrate intake of 30-90 g/hour during exercise fuels prolonged activity and delays fatigue by maintaining blood glucose and muscle glycogen levels.Strong
- Beta-alanine supplementation increases intramuscular carnosine levels by 40-80% over 4-6 weeks, which buffers hydrogen ions during high-intensity exercise to delay fatigue in efforts lasting 1-4 minutes.Good
- Sodium bicarbonate supplementation of 0.2-0.3 g/kg body weight, taken 60-90 minutes before exercise, buffers acid buildup to improve high-intensity cycling performance (1-10 minutes).Good
