Intro: This covers Fast NEGATIVE SPLIT Long Run - 18 Miles In Marathon Training by The FOD Runner. The key takeaways so you can structure a similar session. Watch the full video for the nuances.

Key points:

  • Negative split: easier, hillier opening half shifting into progressively quicker running, finishing at marathon effort.
  • Most of the work is Zone 2 (steady, moderate), with a marathon-effort pickup in the closing miles.
  • Paces were unscripted. The runner used effort-based pacing, starting around 6:44/mi and dropping to around 6:30/mi by the end.
  • Fuel: 200 ml water with 200 g Molad dextrin in a soft flask, gel-like drink.
  • Stay sensitive to fatigue, ease up if it creeps in, and use the hills early to build strength.

Workout example:

  1. Warm-up / Zone 2: around 10 miles on rolling terrain (around 6:44/mi). Take the major hills from the start.
  2. Mid-run checkpoint: at around 1 hour 30 minutes (12 miles), check in. If energy is solid, gear up for a marathon-effort push.
  3. Speed phase: build pace steadily over the next 4 to 6 miles, aiming for around 6:30/mi or quicker.
  4. Final segment: sustain strong effort for the last 2 to 3 miles at around 6:30/mi. Total around 18 miles (near 2 hours 1 minute).
  5. Fuel intake: drink the water-dextrin blend steadily throughout, more before the speed phase.

Closing note: Try this hill-forward negative-split with a marathon-pace finish. Adjust paces in the Pacing app.
