Do you get crazy nervous before triathlons? Try this strategy from Dr. Simon Marshall and Lesley Paterson.

You don’t have one brain—you have three; your ancient Chimp brain that keeps you alive, your modern Professor brain that navigates the civilized world, and your Computer brain that runs your habits (good and bad). They fight for control all the time and that’s when bad things happen; you get crazy nervous before a race, you choke under pressure, you quit when the going gets tough, you make dumb mistakes, you worry about how you look.  Dr. Simon Marshall and Lesley Paterson are here to help you win the brain fight with their new book, The Brave Athlete.
