If you’re a running coach, you know that feedback cadence is as important as feedback. On a race-by-race basis, you’re giving a lot of encouragement and small pieces of feedback. You don’t do major overhauls of training and technique between every race; you need more data than that. You likely do that between seasons.
And you definitely don’t stop your runner mid-race to critique their running before sending them back in, hoping they’ll win.
Feedback has an opportunity cost. Leverage it correctly.
