Ewan Heritage on Instagram: "The workout that helped me run 15:21 for 5K Session: • 3K warm-up + drills & strides • 3K @ 3:45/km • 400m jog • 2K @ 3:35/km • 400m jog • 6 × 400m @ 3:00/km (60s rest) • 5 × 200m in 32–30s (200m jog) • 3K cool-down Why it works: • The 3K + 2K builds strength to hold pace under fatigue • 400s develop VO₂max and race rhythm • 200s sharpen leg speed for a strong finish Do it 10–14 days before race day for maximum benefit. #5KTraining #SpeedSession #TrackWorkout #Runnin
