Is fasted running sabotaging your performance? Are you accidentally under-eating on your hardest training days? This week, we break down the seven most common nutrition mistakes runners make, from calorie restriction at the wrong time to blindly copying elite protocols, and explain why the science says you probably need to eat more, not less.
