We watched “Olympic Marathoner Stephen Scullion + Pro Elite Under Armour Team coach Stephen Haas share all! Q&A” from The Welsh Runner. The conversation is worth your time. The main lessons are below so you can try the workout idea. The full video has the rest.

Key points

• Volume and intensity balance: ahead of Tokyo, Scullion logged about 78 miles a week over a 12-week block, with 35-40% at hard intensity (threshold and VO2-max). The lesson: total mileage matters less than the quality of what you do.
• Training log clarity: a simple colour-coding system (VO2-max, threshold, easy) makes it obvious how much falls into each bucket and how long it’s been since your last hard day.
• Marathon-specific sessions: combine steady long runs with marathon-effort repeats. For example, 2 km reps slightly faster than goal marathon pace separated by easy 1 km floats. Builds specific endurance without overloading.
• Pace distribution: true marathon-pace running is about 20% of the week or less. The rest splits between threshold and easy aerobic running.
• Nutrition: practice your gel strategy in training, especially water-based gels, so you don’t blow up on race day. Treat fueling like medication.
• Data: HR, lactate, and glucose readings are useful, but don’t let them drive every decision. Learn your own thresholds and use the metrics to refine training.
• Mindset: find a mental strategy that fits you. Forcing yourself into a framework that doesn’t is the fast way to lose motivation.
• Stride and cadence: cross-check foot-pod or GPS data with another source. To increase stride length, gentle strength and flexibility work helps.

Workout example (marathon build-up)

1. Warm-up: 2-mile easy jog.
2. Main set: 5 × 2 km just above marathon pace (5-10 s faster per mile than goal), with 1 km easy float between reps.
3. Cool-down: 2 miles easy.
4. Weekly structure: one long run (18-22 mi at steady marathon effort), 2-3 threshold or VO2-max sessions (hard mileage ≈30-35% of weekly total), and easy aerobic running for the rest.

Distances in miles.

Closing note Adapt paces based on your recent racing. Log sessions in the Pacing app to track the balance of hard and easy miles.
