Paula Radcliffe’s world record marathon pace is the focus of a This Messy Happy video. Below is a summary of the key insights and a workout you can test yourself. Watch the full video for more context.

Key Points:

• Radcliffe’s 2003 record required holding 3 min 13 sec per kilometre (≈ 5 min 10 sec per mile), or roughly 18.7 km/h (≈ 11.6 mph) throughout the race.
• When Mary tested this pace on a treadmill, she sustained it for about 600 m (≈ 0.6 km) before the intensity became too much.
• Three elements make this speed sustainable: high step cadence, controlled heart rate, and a thorough warm-up to prevent injury.

Workout Example:

1. Warm‑up – Start with 10 minutes of easy running, then do 4 × 30‑second accelerations to raise your cadence.
2. Main set – Target 3:13/km (5:10/mi) on a treadmill or flat surface. Pick a distance you think you can hold (400 m, 600 m, 1 km work well). Maintain steady effort; when your form starts to slip, end the repetition there.
3. Cool‑down – Finish with 5‑10 minutes of easy jogging, keeping your stride relaxed and natural.

Practical Tips:

• Monitor your pace per 100 m with a watch or app, targeting a step rate of 180‑200 steps/min.
• If you’re new to this speed, start small—try 200‑400 m repeats and build up the distance as your legs adapt.
• Keep the treadmill at 0% incline to match flat road running.
• Stop if your breathing becomes strained or your technique breaks down—recovery comes first.

Closing Note: Give the 3:13 km pace a try, adjusting your intervals through the Pacing app to fit your current fitness. Train smart, stay injury-free, and keep working toward faster times. 🚀
