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:
- Warm-up / Zone 2: around 10 miles on rolling terrain (around 6:44/mi). Take the major hills from the start.
- Mid-run checkpoint: at around 1 hour 30 minutes (12 miles), check in. If energy is solid, gear up for a marathon-effort push.
- Speed phase: build pace steadily over the next 4 to 6 miles, aiming for around 6:30/mi or quicker.
- 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).
- 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.
