You may have better luck with the lifting with a little more carbohydrate and protein than what PB is doing. But you can do the running and biking just fine so long as you truly build your aerobic base like Phil Maffetone describes. If all your physical activities are running on glycogen, you are a lot less fit than you think you are. Train low, race high (carb that is) is often a strategy for running.
