Normalized Graded Pace

Every running distance, outside of ultras and trail races, is time. You know, f you're doing a tinke, what's what barrier? Or marathon, what barrier you trying to break? Forty minutes? Forty five, 35, 30 minutes a it's not are you trying to hold 97 % of your threshold re you trying to improve your threshold. It's also creating, for me, as a coach, like a far better comparison tool. No roads or trails are created equal.
