Intro

A breakdown of “Momentum is EVERYTHING during marathon training | 8 miles tempo” from Stephen Scullion, Olympic marathoner. The video’s worth watching. The key takeaways are below so you can try this workout today.

Key points

  • Momentum matters. After a missed or tough session, go back to simple steady running and protect your rhythm.
  • Adjust, don’t abandon. A tough session deserves modification, not cancellation. Cut the volume (8-10 miles down to 6-8) or reduce intensity rather than skip the run.
  • 800 m alternates: a solid example of tough but manageable tempo work. See our Mastering Interval Training: Science-Backed Workouts and How a Smart App Can Personalize Them for context. The pattern is 800 m faster than marathon pace, then 800 m slower. Effort stays steady while you recover.
  • Pace guide: the hard 800s sit in 10K-half-marathon territory. Scullion runs roughly 4:50 per mile. Our Mastering the 10K: Proven Training Plans, Pace Strategies, and How a Smart App Can Elevate Your Performance guide helps you find this effort. The easy 800s sit just below marathon pace (Scullion’s about 5:20 per mile). Pick a rhythm you can hold across all 6-8 miles.
  • Mindset: ignore the splits. Find your rhythm and trust yourself.

Workout example

  • Warm-up: easy jog and dynamic stretching.
  • Main set (6-8 miles total):
    • 800 m fast (roughly 4:50/mi), then 800 m easy (just below marathon pace, about 5:20/mi). Repeat.
    • Keep alternating 800 m fast and 800 m easy until 6-8 miles total. Adjust the rep count to your distance.
    • You’re building strength and learning to hold effort, not sprinting at 5K pace as in Mastering 5K Speed: Proven Interval Strategies to Cut Minutes off Your Time. Hold between 10K and half-marathon intensity. Keep the easy sections honest.
  • Cool-down: easy jog and stretch.

Closing note

Try this tempo workout. Adjust paces to your marathon goal in the Pacing app and keep the consistency going.
