I have as strong cup of real espresso every morning. Then, mineral water and fresh fruit juices. Any processed alternatives are no good. Two weeks before a race I stop drinking coffee. Then, on the morning of the race two cups of coffee and I am like a tiger. Some coke during the race and I am breaking records.
Caffeine is the only drug I take. I do not take any other drugs. I don’t drink alcohol and I don’t even take other legal performance boosting crap and any other foods that comes in powder. I have not been gifted with the genes to allow me to ever be an elite athlete. I do it for fun, fitness and health. I find it absolutely pointless to use anything that may damage my health.
