Intro: This summary captures Fast NEGATIVE SPLIT Long Run – 18 Miles In Marathon Training by The FOD Runner, a workout worth studying. We’ve pulled the key takeaways so you can structure a similar session today. Watch the full video for all the nuances.
Key Points:
- The workout builds around a negative split: easier, hillier opening half that shifts into progressively quicker running, finishing at marathon effort.
- Most of the work falls in Zone 2 (steady, moderate), with a marathon-effort pickup in the closing miles.
- Paces were unscripted; the runner relied on effort-based pacing, starting around ~6:44 /mi and dropping to ~6:30 /mi by the end.
- Fuel strategy: 200 ml water combined with 200 g Molad dextrin in a soft flask, creating a gel-like drink.
- Key takeaway: stay sensitive to how tired you feel, ease up on the acceleration if fatigue creeps in, and use the hills early to build strength.
Workout Example:
- Warm‑up / Zone 2 – Start with ~10 miles on rolling terrain (roughly 6:44 /mi), working the major hills from the start.
- Mid‑run checkpoint – Once you hit around 1 hour 30 minutes (12 miles), check how you’re feeling; if energy is solid, gear up for a marathon-effort push.
- Speed phase – Build your pace steadily over the next 4–6 miles, aiming for ~6:30 /mi or quicker, maintaining the negative-split structure.
- Final segment – Sustain strong effort for the last 2–3 miles at roughly 6:30 /mi, hitting about 18 miles total (near 2 hours 1 minute).
- Fuel intake – Drink the water‑dextrin blend steadily throughout, stepping up your sips just before the speed phase begins.
Closing Note: Try this hill-forward negative-split run with a marathon-pace finish—adjust the target paces in the Pacing app to match where you are now. Stay attuned to your effort, trust your training, and enjoy the work.
