Here’s an interesting article about the effects of caffeine on working out (running and otherwise). As Gina Kolata points out, caffeine is entirely legal as a performance enhancer; however, reading about how people now wish they had taken caffeine prior to competing makes me feel a little squeamish.
What do you think? Will you start popping caffeine pills before your next race? Maybe I should just make a run to Starbucks before my upcoming 5k–speed training be damned!
