Intro

Here’s a quick rundown of “Run 20% Faster with ONE Simple Change!” by Lee Grantham. It’s worth watching—we’ve summarized the key points so you can test this workout this week. Watch the full video for complete details.

Key Points

• Focus on one excellent interval session each week, not just more miles. Check out mastering interval training to understand the research behind this approach.
• Quality beats everything — nail your execution (10/10) while holding perceived effort at 8/10, which lets you stay the course without torching yourself.
• Warm‑up, fueling, and cool‑down are the backbone that transforms an ordinary interval workout into genuine super‑compensation.
• Match your carbs during training to what you’ll consume on race day—this conditions your gut and accelerates recovery.

Workout Example (Mid‑week Interval Session)

1. Warm‑up – 10–12 minutes of easy running, followed by 2 × 2‑minute efforts at your target interval pace (approximately 8/10 effort). Add another 5–6 minutes if you need more time to elevate your heart rate and leg readiness.
2. Main Set – 6 × 1‑mile repeats at your target marathon race pace, with 60 seconds recovery between each. Maintain the same effort on every repeat; avoid the shock of the early reps. This session targets marathon endurance, but the same principle matters for any distance. Try adapting it for 10K training or for breaking your 5K time.
3. Fueling – Take in carbs at your race-day rate (gels, sports drinks, etc.) throughout the repeats to keep your glycogen topped up.
4. Cool‑down – After the final repeat, drop the pace steadily: jog easy, then gradually reduce intensity until you’re in zones 1–2, wrapping up with a walk.

Practical Tips

• Treat this interval session as your most critical weekly workout—put in a 10/10 performance.
• Aim for 8/10 perceived effort; you want to feel strong, not destroyed.
• Stick to the same warm‑up and fueling approach every week to build a pattern that works on race day.
• Mix this top-tier session with easy runs, recovery runs, and rest days to get the full super‑compensation effect.

Closing Note

Try this dialed-in interval workout next week, and adjust the paces in the Pacing app to fit your current fitness. One well-executed session can shift you closer to that goal marathon time—keep the drive and watch the improvements roll in
