I Tried to Hold 4:20/km... Here's What Happened

In this video, I head to the track for a challenging 4 x 1200m session, aiming to hold a consistent pace across all four reps. As a 46-year-old runner training for faster 5K and 10K times, sessions like this are designed to improve endurance, pacing, and mental toughness. The goal wasn't to sprint the reps—it was to stay controlled and finish strong.
