Normal Runners Try Running at WORLD RECORD Pace - This Messy Happy

Aug 13, 2025

Intro: This is a quick summary of Normal Runners Try Running at WORLD RECORD Pace from This Messy Happy. It’s a fun watch — we’re breaking it down so you can try the workout today. Be sure to check out the full video for all the details.

Key Points:

The crew used a standard 400‑m track to test how long they could hold actual world‑record paces for 100 km, marathon, half‑marathon, 5 k, etc.
They treated the session as a “fun” interval workout, starting with the fastest pace (100 km record) and stepping down to shorter distances.
Pacing is expressed in minutes per kilometre; the 100 km record pace is ~3 min 56 s per km (≈3:56 / km), marathon WR pace ~1 min 16 s for 400 m, half‑marathon WR pace ~36 s for 200 m.
Practical tip: use a track’s consistent 400 m loops, a stopwatch, and a wind‑assist (tail‑wind) for the 200 m attempts.

Workout Example:

Warm‑up – 10 min easy jog + 4 × 100 m strides.
1 km @ 100 km world‑record pace – target 3 min 56 s per km (≈3:56/km).
400 m @ marathon WR pace – aim for ~1 min 16 s (≈1:16/400 m).
200 m @ half‑marathon WR pace – aim for ~36 s (≈36/200 m).
Optional 200 m @ 5 k WR pace – ~30 s if you want an extra challenge.
Cool‑down – 5 min jog + stretch. Adjust the paces to match your own speed using the Pacing app; the key is to hold each effort for the set distance, not necessarily to hit the exact world‑record time.

Closing Note: Have fun turning these insane paces into a playful interval session! Try the workout, tweak the distances or paces to suit your fitness, and let the Pacing app help you stay on track. Keep pushing your limits and enjoy the run!
