Training tip: Easy/recovery runs should be at 60–70% of your max heart rate — roughly 1–2 min/km slower than your race pace. Tempo runs sit right at your lactate threshold, typically sustainable for about an hour. Interval (VO₂ max) sessions are short, hard efforts at near-max effort with recovery between reps.
