Quick summary of The BEST RUNNING training is FINDING what works for you from Stephen Scullion - Olympic marathoner
Here’s what Stephen covers in his video – you’ll find more detail, additional context, and bonus insights by watching the full episode.
Key concepts
- Self‑analysis beats blind‑following: Review your strongest races, identify the training that led up to them, and treat that pattern as your own reference guide.
- Volume of quality intensity: Skip the endless slow-paced running. Instead, Stephen advocates for substantial work performed at challenging intensities (threshold or slightly higher) to see faster gains.
- Threshold vs. Aerobic‑PAR: Threshold means steady, low-lactate work; Aerobic‑PAR pushes a notch higher, just past threshold. Each has merit—try both and observe where your body makes the best gains.
- Sustainable pacing: Maintain consistency by running repeatable sessions each week—the effort should feel maintainable, never exhausting.
Example workout (the session Stephen runs)
- Warm‑up – 10–15 minutes of easy jogging followed by a handful of brief accelerations.
- Main set –
- 3 × 2 km working at a threshold effort (below lactate threshold, challenging but controlled).
- 6 × 1 km at a slightly faster Aerobic‑PAR intensity (surpassing threshold by about 10–15 seconds per km).
- Between the 1 km reps, include either a short trot or 30 seconds of easy movement.
- Cool‑down – 5–10 minutes of easy running.
For a shorter alternative, Stephen offers: 8 × 1 km with roughly 1 minute of jogging between each (approximately 10 km total) at a difficult yet manageable pace.
Practical tips you can use today
- Identify your “winning pattern.” Jot down the training from 2–4 weeks before your best race. Return to those same key sessions.
- Use feel or HR: Without formal testing, rely on perceived effort (difficult yet manageable) or track your heart rate staying just shy of your threshold.
- Track progress: Run the same workout every 7–10 days, logging time, heart rate, and how it feels. Change the intensity only once you’re performing faster consistently.
- Stay flexible: If a session feels light, increase the pace slightly; if it feels too hard, dial it back. You’re aiming for a workout you can repeat and gradually improve.
Closing note
Give the 3 × 2 km + 6 × 1 km workout a try this week and record how it compares to your recent training. Tailor the paces to your own heart‑rate zones or felt intensity using the Pacing app, where you can adjust distances and recovery periods to suit your timetable.
Best of luck with the session, and be sure to check out Stephen’s full video for the complete context and additional details!
