Brad and Andrew get deep into big questions endurance athletes might want to ask themselves about their training - How do I feel? Should I alter my planned workout accordingly? Am I progressing with my fitness, or falling into an overtraining/overstress pattern? Is it okay to "fiddle around" at most of your workouts? (Andrew says YES, and cites an Olympic gold medal swimmer who did just that in his glory days). Enjoy a thoughtful discussion that may change your entire outlook on your endurance goals!
