Intro: Here’s a quick overview of I RAN A 2:48K PACE 400M REP… THEN BLEW UP! Chasing 15 from The FOD Runner. It’s an excellent watch—we’re walking through the key points so you can try the workout right away. Watch the full video to see all the details.

Key Points:

• This speed-focused interval session is built to sharpen 5K pace and work toward breaking the 16-minute barrier. It’s a solid practical demonstration of the techniques covered in our guide to Mastering 5K Speed: Proven Interval Strategies to Cut Minutes off Your Time.
• Warm‑up includes a 3‑mile easy run plus drills/strides (high‑knees, butt‑kicks, skips) and four 20‑second strides to activate the fast‑twitch muscles.
• Main set: 8 × 400 m repeats followed by 4 × 200 m repeats, each with about 75 seconds of recovery.
• Target paces hover around 4:30–4:40 min/mi for the 400 m reps (≈1:07–1:10 per 400 m) and slightly faster for the 200 m reps.
• Avoid pushing all-out—the runner hit a painful tie-up when going too hard in the second half of the workout.

Workout Example:

1. Warm‑up – 3 mi easy + drills (high‑knees, butt‑kicks, skips) + 4 × 20‑sec strides.
2. Main set:
   • 8 × 400 m @ ~1:07‑1:10 each, 75 sec recovery (jog or walk).
   • 4 × 200 m @ ~30‑34 sec each, 75 sec recovery.
3. Cool‑down – 1‑2 mi easy, focus on steady breathing. Tip: If 75 sec recovery feels too short, add a few extra seconds; if it’s too long, trim down. The length of your recovery makes a difference—adjusting it helps you stay just under your lactate threshold. Learn more about the science behind this in our guide to Mastering Interval Training: Science-Backed Workouts and How a Smart App Can Personalize Them.

Closing Note: Give this speed-interval session a shot and observe how your 5K pace improves—feel free to adjust the paces in the Pacing app to match your current fitness. Enjoy the workout, stay healthy, and keep pushing toward those sub‑16‑minute 5K targets!
