Athletes (cyclists included) have a LOT of chemical supplements available to enhance performance.
From caffeine to nitrates to acetaminophen to straight up carbo supersaturation.
My question to those cyclists who do use these LEGAL substances is: how do you know what’s fuelling your performance – you or your chemical additives?
Does anyone ever do a training ride or a race on just pasta and water to see what the difference is?
(Full disclosure: I totally use carbs and caffeine.)
