Better running doesn’t come from one quick fix. Small, consistent habits can add up, and there’s more to it than simply clocking up the miles.
In part two, I explore five practical ways to support your running: dynamic warm-ups, drills, plyometrics, strides, and strength and conditioning. Plus, how to fit them into your week without making training another full-time job.

More isn't always better. In this episode, I explore why the biggest improvements often come from making the training you're already doing more effective - not simply adding more miles, races or sessions.
I look at recovery, strength training, consistency and why quality almost always beats quantity over the long term.
