Negative thought: Your swim goes much slower than expected and you feel like your day is ruined by a bad start.
Combat it: “Wouldn’t it be nice if a good swim meant that your race was in the bag?” Winsberg says. “The same way that a good swim is no guarantee of a good race, a bad one doesn’t predict anything either. Good racers know that you keep racing until the very last step. People can fall apart in the last three miles of the marathon. You just don’t know what’s going to happen‑it’s a long day, and there is plenty of time to correct for mistakes.”
